Add compile_data for android apps

Compile_data is a property on rust rules to declare extra files
that are used by the compiler. In rust's case this happens commonly
with `include_str!()`.

Other compilers like javac or aapt2 don't often reach out to other
files, so it's not as neccessary. But they will follow symlinks.
We're making a change to only include symlinks themselves in sbox
sandboxes, and the targets of the symlinks must be listed
explicitly. For this, we need compile_data to list the targets
of symlinks.

Bug: 307824623
Test: m out/soong/.intermediates/frameworks/base/tools/aapt2/integration-tests/SymlinkTest/AaptSymlinkTest/android_common/lint/lint-baseline.xml with the symlink change
