The Frame runs Android apps in a container (Lepton) that has no OpenXR
loader broker, so the APK needs its own loader. This adds a "frame" build
type: ./gradlew assembleFrame.
It's release plus:
- applicationId .frame, minSdk 30 (the container is Android 11)
- a manifest overlay that drops the headtracking requirement and the
Quest/Pico metadata, since the install fails with it
- the Khronos loader 1.1.63, fetched from Maven Central at build time,
checked against a SHA-256 and unpacked into build/ (not committed)
- L1VR_STEAM_FRAME for the native code, BuildConfig.STEAM_FRAME for Java
Quest builds don't see any of this. I also added the gradle wrapper script
to Projects/Android, since the wrapper jar and properties were already
there, and -Wall for the VR sources.
Haven't run it on the headset yet.
