This CL passes the offset and uri of the file (here called a script uri
as opposed to a library uri, the two will be different if we're in a
part) when doing expression compilation.
This CL only passes the data, but doesn't actually use it.
Future CL(s) will use this data to calculate the static type of
available variables which is needed for an upcomming feature.

Creation of AppJit snapshot will not include the source of [Script]
objects (see `UntaggedScript::snapshot_to`). As a result there's no
point in letting the CFE embed the sources into the kernel if we
only use it to create an AppJit snapshot.
This is also in line with build rules for our dart-sdk, where we do the
kernel compilation separately, see utils/application_snapshot.gni:
```
template("application_snapshot") {
...
# Build the kernel file using the prebuilt VM to speed up the
# debug and simulator builds.
prebuilt_dart_action(target_name + "_dill") {
...
args = [
...
"--no-embed-sources",

[[[

As part of implementing hot-reload for isolate groups, we have to ensure
reloads on a group are performed using the same state of incremental
compiler.
This means we cannot use a specific isolate's information (such as it's
main port) for reloading purposes. Instead we use the unqiue isolate
group id when communicating with the kernel service.

TEST=Existing test coverage, future test when hot-reload is fully
implemented with isolate groups.

Previous version
(landed via https://dart-review.googlesource.com/c/sdk/+/135683)
only worked if the dill was loaded via
Dart_LoadScriptFromKernel where script_kernel_size was set,
and when the platform dill could be loaded from a file called the right
thing.
This CL makes it work for Dart_LoadLibraryFromKernel too and allows
the VM to send the platform along (explicitly or implicitly) and only
tries to load the platform from a file with the right name if no
platform is given in any of the inputs.
This should fix http://b/148776866

Discovered using the DevTools widget inspector with a Flutter
application which did not have a flutter_tools instance connected. The
widget inspector attempts to evaluate expressions, the VM service
realizes there's no external compilation service and attempts to fall
back onto the kernel isolate's compilation service. The crash occurs as
KernelIsolate::InitializeState had not been called during initialization
as Dart_InitializeParams.start_kernel_isolate == false.

Whenever the VM sends a request to evaluate an expression, it sends over
the list of alive dills (in order) and a sequence number (number of
reloads).
This can then either be
a) ignored if there's already a compiler around that has compiled
everything itself (e.g. if launched from source with observatory
enabled).
b) used to find out that we need to create a new compiler especially
for expression compilation. Either because we don't have any old
compiler or because a reload or GC changed the data available.
c) used to find out that the compiler we created previously is still in
a good state.
Tests for expression compilation has been added, and with the "framework"
added it should be easy to add new ones.
This CL leaves a few things to possibly be improved later:
* It doesn't support if one tries to do a mixed mode, where one
starts from source and reloads from dill. The compiler will not be
updated and the expression compilation will work on a old view of the
world.
* If - in any of the reloads - the main entry point changes library,
the initialization might not work correctly.
Fixes#34736.
