In the client.webrtc waterfall we're lacking compile coverage of Android Debug builds with is_component_build=true set. Chromium has this in https://cs.chromium.org/chromium/src/tools/mb/mb_config.pyl?rcl=0&l=470 as an example.

Let's call the new bot ''Android32 ARM Builder component (dbg)'

I've verified the build is currently green as of [1] using:
gn gen out/android-Debug-component --args="target_os=\"android\" target_cpu=\"arm\" is_debug=true is_component_build=true"
ninja -C out/android-Debug-component
