AAPT2: Add workaround for non-standard package IDs

The dynamic ref table used to map build-time IDs to runtime IDs
is mainly used for shared resource libraries and has a few built-in
mappings (app 0x7f and framework 0x01).

Using a non-standard package ID like 0x80 causes a failure in package ID
lookup. The solution is to ship the dynamic_ref_table with an identity mapping
with any resource table that uses a non-standard package ID.

Adds some tests to ensure this works correctly.
