Add android rule helpers and cleanup input loops
This change teaches the configure script how to search for Android NDK and SDK installations and create new WORKSPACE rules pointing to them. It also refactors many similar loop-over-user-input functions into using a reusable method (not the more complex ones). Specifying an SDK directory will further query for the available SDK API levels and build tools versions, but it won't perform any compatibility checks. Like other settings, every android-related setting can be set beforehand via an env param. The script will not ask for any Android settings if there are already any android repository rules in the WORKSPACE. The script will emit a warning if using an NDK version newer than 14 due to https://github.com/bazelbuild/bazel/issues/4068. PiperOrigin-RevId: 177989785
