build: Bump AGP to 9.2.1 and migrate Android modules (JAVA-649)

Raise the minimum AGP to 9.0.0 (default fallback 9.2.1) and perform the
AGP 9 migration: refresh the AGP-compat matrix (9.0.0/9.1.1/9.2.1), add
the AGP 9 opt-outs (android.builtInKotlin/newDsl, lint 9.2.1), pin Java
and Kotlin targets to 8 across the Android library modules, set
testBuildType to release for unit tests (including sentry-compose), bump
the uitest modules to JVM 11, and resolve the AGP 9.2 lint findings.

Robolectric 4.15 caps at API 35, so pin the affected tests with
@config(sdk = [35]) to keep them green against targetSdk 36. lint 9.2.1
flags compileSdk 36 as outdated (37 is available); disable GradleDependency
for the Android modules since the SDK bump lives in the API 37 PR.

Split out from the API 37 bump (#5768) so the toolchain upgrade lands on
its own. compileSdk/targetSdk stay at 36 here.
