Android testbed: ensure managed emulator has 4GB RAM
PR Description (paste into GitHub)
Fixes #144418.

The Android testbed’s Gradle Managed Devices sometimes create AVDs with only 2 GB RAM, which is borderline for running CPython’s test suite and requires manual post-creation edits. This change makes the RAM setting reproducible (including on fresh VMs like GitHub Actions / cibuildwheel users) by patching the managed AVD configuration after creation.

Changes

Adds minVersionPatchAvdRam / maxVersionPatchAvdRam Gradle tasks that set hw.ramSize=4096 in the AVD’s config.ini and hardware-qemu.ini.
Ensures the patch runs automatically:
after each *Setup task, and
before each *DebugAndroidTest task (so the RAM fix applies even if *Setup is up-to-date).
Locates the managed AVD robustly (uses .ini pointer path= when present; supports Windows paths and Gradle’s gradle-managed/ directory).
Removes the manual “edit hw.ramSize” paragraph from Android/README.md (the emulator is now configured automatically).
Makes Android/android.py require ANDROID_HOME lazily (only when SDK/adb is needed), which helps setup flows that download the Gradle wrapper before SDK configuration.
Testing

Windows:
.\gradlew.bat :app:minVersionSetup --rerun-tasks (observed minVersionPatchAvdRam logging ramMb=4096)
.\gradlew.bat :app:maxVersionSetup --rerun-tasks (observed maxVersionPatchAvdRam logging ramMb=4096)
Notes

Android/testbed/local.properties may be used locally to point Gradle at the SDK on Windows, but it is not intended to be committed.
If you want, I can also give you a one-liner “PR checklist” (branch name, exact git add, commit message, push, PR link) tailored to your fork remote names.
