AOSP Music to bazel: Added BUILD file

The new Bazel BUILD file will replace the Android.bp
file. Moreover, the glob function was altered so that
the res directory can be accessed without copying
and without the addition of another BUILD file.

Test: manual - to test how the AOSP Music app builds
with Bazel, I ran: "b build :Music --fat_apk_apu=k8"
in the packages/apps/Music directory. The APK can
be pushed onto the phone using:
"adb install -r -d -t *path of Music.apk*"; however,
because Soong/AOSP and Bazel use different APK signers,
the app can only be pushed onto a phone with a release
build flashed. Currently, either Bazel must support
.pk8/.x509.pem pairs or these file types must be
converted to .keystore.
