Add ApexInfo.RequiresLibs to mixed build handler for apex

Adding ApexInfo.RequiresLibs from Bazel to apexBundle.requiredDeps which is eventuallyread by apex androidmk writer for LOCAL_REQUIRED_MODULES to ensures the libs are installed as part of a bundle build.

In Soong, apexBundle.requiredDeps is set in
https://cs.android.com/android/platform/build/soong/+/master:apex/apex.go;l=2305-2323;drc=cb7e73bc0130a95f5991c925c349387185abc098

The same logic is replicated in Bazel at
https://cs.android.com/android/platform/build/bazel/+/master:rules/apex/cc.bzl;l=141-163;drc=cb7e73bc0130a95f5991c925c349387185abc098.

This CL is porting the required libs set by Bazel in mixed build.

Test: go test
Test: run build/bazel/ci/mixed_libc.sh
