[aapt2] Fix aapt2 diff for added/removed resources
The old implementation used to iterate over both apks in
parallel, making the whole output wrong as soon as they
get out of sync because of an added or removed resource.
New code performs a lookup for each resource, making it much
less efficient (quadratic complexity), but actually produces
useful output.
Performance is enough to run a framework-res.apk diff in
milliseconds - no need to make a lookup table.
+ print the output into STDOUT instead of STDERR, as it's
supposed to be
+ add a --ignore-id-shift command line flag to skip printing
differences in IDs if those are the only differences. Any
added or removed resource will make all subsequent IDs change,
making the output almost unusable
Bug: 396020063
Flag: EXEMPT bugfix
Test: manual on framework-res.apk
