In some build targets/combinations aconfig_flags.pb
may not be generated.
For example in GSI only system/aconfig_flags.pb exists
and system-only updates won't have vendor/aconfig_flags.pb.
Test: m, aflags

aconfig_device_paths uses `include_str!` to include a text file
containing comma-separated strings with each partition aconfig file.
The lib does not handle the escaped newlines and quotation marks.
Adds proper handling.

Create one library for reading protos from all containers, instead of
having numerous libraries perform the same logic. For Java, we will
create a similar library reusing the same
partition_aconfig_flags_paths.txt.
Bug: 324436145
Test: adb shell aflags list # Confirm that various containers appear
