This reverts commit 8e73bab9.

Implements the following:
  - If both --host-vmservice-port and --dds-port are specified, use the current behavior
  - If only --host-vmservice-port is specified and dds is enabled, use that for the dds port
  - If only --dds-port is specified, use that for the dds port

[flutter_tools] use initially parsed package config for language version, sound mode determination (#70323)

[flutter_tools] remove branch migration and standardize constructor style for version interface (#70058)

Disabled caching of pub invocations on flutter drive.

This reverts commit ff953e4f.

Necessary to work around #70013 (this looks like it will be fixed, but should protect us in the future)

Restores some notion of skipping pub, with differences from the prior implementation:

Off by default, and only used by the flutter command automatic pub get
A single check parameter. Uses the framework version cached per-project instead of a timestamp of the tool, to avoid cases where downloading a prebuilt framework would cause this check to no longer work.

This reverts commit 6e5845f0.

initialize the flutter root as early as possible. This allows all interfaces to be normally injected into commands, even if those objects might read from the flutter root.

[flutter_tools] support --extra-gen-snapshot-options everywhere --extra-front-end-options is specified (#69592)

support --extra-gen-snapshot-options everywhere --extra-front-end-options is specified

Disable null safety auto-detection for the web

Support --web-renderer options which would allow user to specify which rendering backend to use. (#68848)

Moves the flutter root initialization to a static method on the cache. This is a small step towards making this functionality non-static and instead injected like normal members - however, completely removing all of the static-ness at once was too large of a change.

Instead document and add unit tests and change existing code as little as possible.

#47161

There have been some more additional reports of a missing 'package:characters' import after upgrading flutter. This has me concerned that our pub caching logic is incorrect. Instead of the tool attempting to guess when pub should be run, always delegate to pub.

Also takes an opportunity to fix the kernel snapshot depending on the .packages or package_config. Due to the generated: date field this causes extra rebuilds. Instead when pub get is run, write out an additional file with just the package contents and version.

Fixes #66777
Fixes #65723

Remove devicelab specific code for shutting down gradle daemon, add --android-gradle-daemon option to build/run/drive`. Avoids need for un-tested devicelab specific handler. There are also some feature requests for this, so 2 birds one stone.

Example:

flutter build apk --no-android-gradle-daemon will pass --no-daemon on to gradle

Do not allow attach in release mode, as there is not VM Service to connect to. Observed in crash reporting as thrown string which is changed to exception below.

This class is entirely superseded by the application package factory. Only drive and install use it, and removing it from drive will allow use-application-binary support.

Fixes #61772

tool exit if there is no file at the path provided when building/running with sksl

HACKTOBERFEST

Remove global variables from compile.dart and devices.dart (except for dds which needs more changes).

This reverts commit 76cbc462.

There have been some more additional reports of a missing 'package:characters' import after upgrading flutter, as well as problems with detecting the correct language version. This has me concerned that our pub caching logic is incorrect. Instead of the tool attempting to guess when pub should be run, always delegate to pub.

Woops, this is breaking Dart's golem benchmarks

Make the logic for locating a local engine path part of its own class, add documentation, and update tests to cover engine source path locating too.
