AAPT2: Ignore trailing data after IEND chunk in PNG
libpng seems to do the same, so our chunk filter should not care what
comes after.
Bug: 38169876
Test: manual

AAPT2: Fix up file IO
This also enables an AAPT behavior that CTS tests have
come to depend on.
Small files that compress negatively (get larger) are stored
uncompressed. Some CTS tests assume this and try to open these
files by mmapping them, which is only possible if they are
uncompressed.

AAPT2: Rename to match new style
Use Google3 naming style to match new
projects' and open source google projects' style.
Preferred to do this in a massive CL so as to avoid
style inconsistencies that plague legacy code bases.
This is a relatively NEW code base, may as well keep
it up to date.
Test: name/style refactor - existing tests pass

Use Google3 style guide with .clang-format
Test: style change only, builds ok

AAPT2: Refactor PngCrunching
PngCrunching now has a slightly better heuristic of choosing to encode
an image as a palette or RGB. For small images, RGB compresses much better
than a palette.
The original PNG is used as-is (minus some optional chunks being stripped)
if the resulting crunched PNG is larger than the original.
9-patch handling is abstracted away from PNGs, paving the way
for other 9-patches, like WebP.
TODO: handle PNGs with 9-patch chunks already present, which
should just be passed through. This will allow for 3rd party
tools to generate 9-patches.
TODO: implement cheap transparency: when one color is used to represent
transparent, and all other colors are opaque.
