Implement a thread safe wrapper for Skottie

This patch implements a thread safe wrapper for the core skottie
animation object. We want to share the same animation resource file for
multiple SkiaVectorAnimation objects. This would allow us to do that.

This is also needed to implement the Phase 2 and Phase 3 of
rasterization where the rasterization would be handled by different
threads.

Cache and load skia animations via resource bundle

This patch implements the ability to load skia vector animation files
via the resource bundle. Each file is only loaded once and cached for
future use. ResourceBundle expects the animation file to be gzipped.

UMA metrics are also recorded to note the time to uncompress and parse
each animation file.
