Bug: b/167743764
Android's RenderEngine is now using Skia, but it doesn't need all the
pieces of Skia used by HWUI. Make a smaller version of Skia that
excludes many of those pieces, in particular where they bring in other
dependencies:
- codecs
- text
- pdf
- xml
Add a new cc_defaults to be shared by the new libskia_mini and libskia.
Manually insert fexceptions into libskia, since it is only needed by
SkRawCodec (not needed by mini).
Add a new SkUserConfig for mini, so it can exclude defines like
SK_CODEC_DECODES_PNG.
Continue to link in libpng (and libz, which it depends on) and build
SkPngEncoder, so that SKP captures can include compressed image files.
Switching to the mini-skia reduces the size of surfaceflinger from 7.4M
to 6.0M.
