[pigeon] Use a shared generation step for platform_tests/ (#2823)

* Reorganize process helpers to reduce duplicate code

* Add wrappers for common process commands

* WIP generation consolidation

* Re-add the Java special casing that the bash version did

* Fix gradlew check

* Add ignores for Dart for now

* Update README

* Typo fix

* Autoformat

* Fix Windows

* Windows command fix

* Try returning to runInShell:true to see if that fixes the CI hang

* Revert more of _runWindowsUnitTests for CI debugging

* Add missed early return for failure

* Verbose build, and disable Dart generation to further reduce differences

* Revert "Verbose build, and disable Dart generation to further reduce differences"

This reverts commit ddfbf8b.

* Revert "Revert more of _runWindowsUnitTests for CI debugging"

This reverts commit e4e867c.

* Revert "Try returning to runInShell:true to see if that fixes the CI hang"

This reverts commit a124e08.

* Fix Windows includes
