Largely mechanical. Only three places that were calling createApprox

GrExternalTextureData is an API for exporting the backend-specific
information about a texture in a type-safe way, and without pointing
into the GrTexture. The new detachBackendTexture API lets us release
ownership of a texture to the client.
SkCrossContextImageData is the public API that lets clients upload
textures on one thread/GrContext, then safely transfer ownership to
another thread and GrContext for rendering.
Only GL is implemented/supported right now. Vulkan support requires
that we add thread-safe memory pools, or otherwise transfer the
actual memory block containing the texture to the new context.

Rob and I spent a long time debugging why this wasn't working for
Flutter - doing the more complex operations on the loading thread
produces a blank texture when it's used later on the drawing thread.
Limiting ourselves to just creating and uploading RGBA data fixes
that. We need to debug what's going wrong, but in the meantime, this
lets Flutter use Skia APIs to manage GPU uploading and lifetime of
texture-backed images, while still doing those uploads on their IO
thread.

This CL makes the GrTextContext be owned (and hidden) by the GrDrawContext. This funnels all the drawText* calls through the GrDrawContext and hides the (dispreferred) GrPipelineBuilder drawText variant.
Some consequences of this are:
GrDrawContext now has to get the text drawing settings (i.e., SkDeviceProperties & useDFT). This means that we need a separate GrDrawContext for each combination of pixel geometry and DFT-use.
All the GrTextContext-derived classes now get a back pointer to the originating GrDrawContext so their method calls no longer take one.
