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.

Revert "[flutter_tools] refactor drive launch into separate service, split by mobile+desktop and web (#68451)" (#68845)

This reverts commit 2e75f52a.

This reverts commit bde85ea3.

* Fix mutiple pointers bug

* Add unit test case

* Remove unnecessary map clone

Fixes a bug where keyboard capitalization mode was exited when pressing clear.

Corrects the space available to the label in an outlined text field

Enables build_test for Windows. Currently only flutter_gallery has platform directories for the desktop platforms, so this will run only that build, but this will provide an end-to-end build test for Windows.

Other example/test projects can be brought online for Windows in the future just by adding the windows/ directory to the project.

[flutter_tools] refactor drive launch into separate service, split by mobile+desktop and web (#68451)

Overhaul of flutter drive in order to deliver a better experience, namely:

flutter run and flutter drive now share more flags, so code paths that were previously only testable on run are now testable on drive.
Removes web-initialize-platform as this is no longer used
flutter drive correctly sets up a logger that shows native exceptions, by connecting to the vm service.
VM service connection now provides access to memory info without launching devtools (only for debug/profile mode)
Web changes

Passes on the one test in the repo, otherwise the webdriver code has been isolated as much as possible

Additional NNBD related bug fixes:

No longer passes --enable-experiment to the test script. (FYI @blasten ). earlier we might have assumed that the flutter gallery benchmarks would be migrated along side the app and flutter driver, but only the app under test needs to be migrated. The test scripts should never be run with the experiment.

Enables build_test for Windows, macOS, and Linux. Currently only
flutter_gallery has platform directories for the desktop platforms, so
this will run only that build, but this will provide an end-to-end build
test for all three desktop platforms.

Once this lands, other example/test projects can be brought online for
desktop platforms in the future just by adding the relevant platform
directories to the project.

Currently the framework handles delete, but not backspace, so embeddings
all have to implement backspace handling themselves. This eliminates
that inconsistency and allows simplified code in embeddings by adding
backspace handling.

It also fixes a bug uncovered in the delete handling where deleting a
selection would also delete the next character after the selection.

* App.framework must support iOS 8 for older Flutter projects

* Fix test

The template uses strcmp (to check the received method), so should
include <cstring>
