Add Android emulator support

Add prebuilts and scripts for the Android emulator
and all the required SDK harness.
Also introduces a run_android_emulator script that
sets up the necessary .avd files and starts the
emulator using the configuration files checked in
into //build/android_emulators.
In the next CLs this will be wired up to tests.

Building from a standalone checkout

If you are a chromium developer and have depot_tools installed you can avoid the build/ prefix below and just use gn/ninja from depot_tools.

  • Run build/install-build-deps to install third-party build deps (NDK etc)
  • Run build/gn args out/android to generate build files and enter in the editor:
    target_os = "android"  # or "linux" for local testing
    target_cpu = "arm"  # or "arm64"
    is_debug = true  # or false for release
    
  • Run build/ninja -C out/android all

Building from the Android tree

TODO. The plan is to autogenerate the Android.bp build files from the master GN build files (or temporarily maintain both until we can autogenerate them). Will come in next CLs.
