rename getSampleCount -> getRenderTargetSampleCount because it will return
0 when a config is not renderable but *is* supported as a texture format.
(Old name kept around until Chrome stops calling it)
Add virtual GrCaps::maxRenderTargetSampleCount(GrPixelConfig).
Devirtualize isConfigRenderable() and implement as maxRTSC != 0. Separate implementation for version with bool withMSAA param to be removed after Flutter is updated to no longer call.
Consolidate various file static GrSurfaceDesc validators fns into GrCaps::validateSurfaceDesc().
