The DartRuntimeService based VM service implementation now has support
for launching DDS instances and responding to _yieldControlToDDS RPC
invocations from DDS instances.
package:vm_service test suite is ~97% passing with this change.

When running a large test file with `solo: true` on one test, the output looks like:
```
! test name
Skip: does not have "solo"
! test name
Skip: does not have "solo"
! test name
Skip: does not have "solo"
! test name
Skip: does not have "solo"
✓ solo test
! test name
Skip: does not have "solo"
```
While custom skip messages might be useful, when the skip messages are from using solo:true this just makes the output spammy and adds extra noise to scan through for the actual solo test you ran.
This change prevents creating output events for such skip messages (but still sends them for custom messages, since those are likely far less frequent).
The `print` events themselves are still forwarded to the DAP client, so it still has the data for this that it can present elsewhere (for example by showing the test node as skipped, if appropriate).

This test was flaky because thread-exit events are not guaranteed because the VM might terminate too quickly and we will instead emit a "terminated" event. Rather than trying to guarantee these events (for no benefit), this just makes the test accept the results with or without the text-exited event as long as we still got the terminated event.

In order for "Copy Value" to work in VS Code's debugger windows, we need to provide an expression for each variable (the "evaluateName"). To carry this down through the child fields we need to store it by the object ID on the server, but we were not doing so for global fields - this resulted in "Copy Value" giving truncated values and "Copy Expression" being missing.
The fix is to ensure we call `storeEvaluateName` for globals too.

While investigating the flaky test at https://github.com/dart-lang/sdk/issues/60187#issuecomment-3431336127 I found that we had two paths into `handleThreadStartup` - one which explicitly sent a "pause-on-entry" event, and one that did not. The method sets a flag so it only ever runs once.
This means depending on which instance of `handleThreadStartup` occurs, the client may or may not get the pause-on-entry event.
The case where it would is where the isolate already had a pause-start event when we found it. The case where it would not, is if the isolate did not have a pause event (for example it was None because the isolate was just being created).
I can't come up with a good explanation for why we would try to pre-emptively run startup for an isolate we just discovered with no pauseEvent, so I have removed this branch on the assumption that we would always then see a `PauseStart` event for the isolate and then handled it through the same code path (and therefore, always sent the `pause-on-entry` event prior to calling readyToResume).

A recent change somewhere caused some Dart-Code tests to fail. The expression "DateTime.now().ye" used to fail to compile and resulted in a failed RCP call to the VM service ("Expression compilation error") but now it returns a valid result that is a `vm.ErrorRef`.
This applies the same regex to the error message in this path to extract the most useful part of the error text when in the "watch" context so that the visible part of the message is not just "Unhandled exception".

Due to variable shadowing and lazy initialization of the DevTools URI
within DDS, the DevTools URI reported by DDS did not include the `uri`
query parameter used to automatically establish connection to the
current DDS instance.
This change updates variable names to avoid shadowing and also fixes
issues where the DevTools URI would be reported even if DevTools was not
enabled in the DDS configuration.

This reverts two commits (in separate patch sets in the CL):
- commit 482a7caed7: [dap] Simplify URI handling in IsolateManager.addBreakpoint
- commit d0a7ef4459: [dds/dap] Add/remove breakpoints as required instead of replacing the whole set
The first revert is to avoid conflicts while reverting the second, and will be reapplied later (likely after the release branch, since it is not critical to include). The second revert is because this change resulted in leaked Script objects in the VM.
There is an additional change (patch set 3) to fix up the changelog/versions so they don't go backwards.

IsolateManager.addBreakpoint was forcing resolution of
google3:// URIs via lookupPackageUris vm-service call which is
not necessary.
addBreakpoint vm-service method is itself capable of handling
both original package:// URIs and their resolved forms (irrespective
of whether resolved form is file URI or a URI with a special
scheme introduced by multi-root filesystem).

- split the Dart CLI tool out of the VM into it's own embedder which
runs in AOT mode. The pure Dart VM executable is called 'dartvm' and
has no Dart CLI functionality in it
- the Dart CLI executable parses the CLI commands and invokes the rest
of the AOT tools in the same process, for the 'run' and 'test'
commands it execs a process which runs 'dartvm' to run
- 'dart hello.dart' execs the 'dartvm' process and runs 'hello.dart'
- the Dart CLI is not generated for ia32 as we are not shipping a
Dart SDK for ia32 anymore (support to execute the 'dartvm' for ia32
architecture is retained)
- the Dart CLI tool is not built in the internal Dart SDK builds

The DAP APIs for breakpoints send the whole set of breakpoints for a given file at once. Previously, we would just delete all breakpoints and then re-add them all, however since we added support for resolving breakpoints, this can result in all breakpoints in a file flickering to unresolved then back to resolved (as well as generally being slower).
This change splits the method that would replace all breakpoints into methods for add+remove, and then skips over any breakpoints (in setBreakpoints) that already match breakpoints we have.

This is follow up to commit cb0c2bf5ed.
SampleBlockProcessor only enters isolate group and not a specific
isolate so the code must not rely on thread->isolate(). This fixes two
places where this was not the case:
* ProfileBuilder::IsPCInDartHeap
* UserTags::TagName
pkg/dds/test/get_cached_cpu_samples_test was supposed to cover this but
it has two problems:
First I observed that SampleBlockProcessor never gets a chance to
process a block if mutator thread always gets to it first (via a
scheduled interrupt), so this code is not well exercised. I started by
adding a variant of the test where interrupts are inhibited via a
vm:unsafe:no-interrupts pragma - which revealed the crashes in the
SampleBlockProcessor code.
This revealed the second problem: get_cached_cpu_samples_test does not
actually fail if testee crashes during the test, it just silently
completes with success. This seems to happen because disposal of
VmService connection is not forwarded into the future on which the test
is awaiting - and the whole process just exits once VmService connection
to the testee disappears (because all ports are closed, no pending
activity is possible after that one). I have fixed this by adding a
helper function which checks that connection to VmService only goes away
when we dispose it.
Note: there is another obvious issue here, which I am leaving unfixed
for now. SampleBlockProcessor calls UserTags::TagName in a way that can
race with isolate itself modifying the table. I think this race is
extremely unlikely but it can cause crashes on ARMs with its weak memory
model (e.g. we might end up reading garbage due to the reordering of
stores).
