Enable Android Platforms by default for Android-related builds
Fixes #16285.
RELNOTES: Enable Platforms and Toolchains for Android. Android projects will need to stop passing the legacy flag `--fat_apk_cpu`, and instead use `--android_platforms` using platforms defined with the `@platforms//os:android` constraint. The https://github.com/bazelbuild/rules_android repository defines four standard Android platforms for projects that use those rules, `@rules_android//:armeabi-v7a`, `@rules_android//:arm64-v8a`, `@rules_android//:x86`, `@rules_android//:x86_64`.
Blog post describing these changes to follow.
Closes #19726.
