AAPT2: Add support to specify stable IDs
The --stable-ids flag allows the user to specify a file containing
a list of resource name and resource ID pairs in the form of:
package:type/name = 0xPPTTEEEE
This assigns the given resource the specified ID. It helps ensure
that when adding or removing resources, IDs are assigned in a stable
fashion.
If a package, type, or name is not found, no error or warning is
raised.
