Fix android full build in CI (#22486)

* Split out android builds to not use as much space during building

* Ensure we can test android builds with act

* Since we use checkout_submodules, submodules are not needed on the other checkout

* Add some documentation on using act to test

* Fix ENOBUFS being undefined when compiling tv-casting-app on arm
