Fix gradle builds for Apple Silicon running arm64 JDKs

[skhamis]

fixes #4665

To Test (Intel or M1 Mac)

1. Delete your libs/desktop folder (should be only darwin in there)
2. If you have any rust.targets in your local.properties update (or just comment out for now):

• Remove any darwin targets
• update to one of the new darwin-specific architectures

2. Run ./libs/verify-desktop-environment.sh
3. also run ./build-all.sh android (shouldn't need rebuild but just incase)
4. you should now see libs/desktop/darwin-{your-arch}
5. in the top level of the project, run ./gradlew assembleDebug
6. using local-published flow, ensure android-components can also build successfully
7. using local-published flow, ensure fenix can also build successfully

• Need to confirm it still works on Intel (will need to clear out libs/desktop and rebuild NSS/SQLCipher)
• Need to be able to successfully build android-components -> fenix with no issues

@tarikeshaq would you mind following the instructions to test that this works on Intel?
@MatthewTighe would you mind also following the instructions to test that this works on your M1 (will need to ensure your JDK is arm64)

[tarikeshaq]

Tested it on my Intel machine! app services builds all the way across the local development flow to fenix/android components. As we debugged yesterday, I had a rust.targets in my local.properties and I need to replace darwin with darwin-x86-64.

We should probably the docs in https://github.com/mozilla/application-services/blob/main/docs/howtos/locally-published-components-in-fenix.md to reference the new darwin-x86-64 and darwin-aarch64 targets instead of darwin

This is blocked until:

• Update room to support M1s with arm64 JDKs mozilla-mobile/android-components#11626
  or
• WIP Update to Kotlin 1.6 mozilla-mobile/android-components#11516

land as any M1s hoping to build a-s and then use the locally published flow in a-c will run into issues with the kotlin library room. While the first PR is much smaller, there is issues raised on the a-c team being that it's a pre-release version and moving to the next stable release will require kotlin 1.6 (second PR).

[skhamis]

While this fixes it in a-s, there will be an issue in a-c with the room library so I won't announce that M1s can use native arm64 JDKs, however given that this is still needed on our side -- I'll land it once all tests pass and let a-c chart the path to fixing it on their side based on their timetables.
