oop: Intergrate skia font remoting for OOP raster.

Integrate SkStrikeServer/SkStrikeClient to remote glyph generation for
OOP raster. This includes the following changes:

1) Use a SkTextBlobCacheDiffCanvas during serialization to analyze text
blobs serialized as a part of raster commands. This is used to track
the set of glyphs that will be required to raster these commands.

2) Use the SkStrikeServer::DiscardableHandleManager to let skia
allocate and lock discardable handles. Each handle is allocated a
unique id that skia can internally serialize and map to an instance
of SkGlyphCache on the GPU process. This allows the renderer to pin
glyph caches on the GPU until dependent raster commands are executed
on the service.

3) In the GPU process, deserialize the font data prior to executing
the raster commands. The deserialization populates the requisite glyph
caches with the glyphs generated by the renderer. Once the raster
commands have been executed, unlock all the discardable handles.
