Ben Konyi 9304826679 [ DDS ] Refactor DDS entrypoint to allow for overriding behavior in google3
This moves the CLI logic into lib/src/dds_cli_entrypoint.dart so it can
be invoked by a custom google3 entrypoint (bin/dds.dart can't be
imported using a package: URI).

Since google3 will be able to perform some custom configuration of DDS,
google3 related logic (e.g., `BazelUriConverter`) is also removed. This
is technically a breaking change, but should be safe as this
functionality isn't currently being used.

Ben Konyi cf9623f3d9 [ DDS ] Update DDS launch sites to assume DDS process closes stderr
Removes risk of DDS connection information being split across two stream

Also updates DDS to close stderr, even in the error case.

Ben Konyi 6eb85949fd [ VM / DDS ] Add --print-dtd-uri flag and launch DTD from the correct snapshot for AOT
This adds support for printing the DTD connection information to stdout
when --print-dtd-uri is passed.

This change also fixes an issue where DDS would fail to spawn an isolate
with the DTD snapshot when DDS was running in AOT mode. This means the
SDK must be shipped with both AppJIT and AOT DTD snapshots, at least
until dartdev is moved to run from AOT.

Ben Konyi 8db4393f1e [ CLI ] Start DDS instance if VM service URI passed to dart devtools doesn't have a DDS connection
This is can happen if a Dart or Flutter application is started in a
non-standard way (e.g., not through the `dart` or `flutter` CLI
tooling). Developers using custom embedders need to use `dart devtools`
to start a DevTools instance, so it's a good opportunity to check for a
DDS instance and launch DDS for the target application if one isn't
found.

Reason for revert: breaks crossword simarm tests https://ci.chromium.org/p/dart/builders/ci.sandbox/vm-kernel-precomp-linux-debug-simarm_x64/2619

Original change's description:
> Reland "[ VM / DartDev ] Launch DartDev in an isolate within a single main Dart process"
> 
> This CL changes how DartDev is run and how the run command handles executing a Dart program (will port additional commands in a separate CL). Rather than using DartDev to spawn a child process to run user code, the VM will instead launch a DartDev isolate after doing some VM options processing. DartDev will communicate information like exit codes and script/arg pairs with the VM via isolate ports. Once DartDev runs to completion and notifies the VM that a script should be run, the VM will move on to spawning another isolate with user code and continue executing in the same VM process.
> 
> By moving DartDev into an isolate within the same process that user code will eventually run in we're able to resolve the following issues that arose due to signal handling and IPC issues:
> 
> VM hangs when --enable-vm-service is supplied and there are compile time errors (https://github.com/dart-lang/sdk/issues/42630)
> Dart daemon spinning in exit code handler / zombie Dart processes (https://github.com/dart-lang/sdk/issues/41978)
> Signal handling in children of 'dartdev run' is problematic (https://github.com/dart-lang/sdk/issues/42092)
