This CL leaves the Ganesh world in a very odd place. In particular it still:
has pendingIO refs on GrSurfaces
forwards the proxy refs on to the backing GrSurface
Removing everything at once only ends in a mess thus, this goofball CL.

Add retain() instead (this will be added to sk_cf_obj as well).
The issue is that Chrome is storing their objects in a unique_ptr<>
style class which wishes to retain ownership, so we can't use reset(),
which transfers ownership.

This is modeled on how we coordinate VkImage layout changes between
GrContext and clients.
A type GrGLTextureParameters is used to track the current parameter
state.
When a client creates a GrBackendTexture in order to wrap a resource
they created a new GrGLTextureParameters is created and the wrapped
GrGLTexture will share ownership.
When GrContext creates a non-wrapped GrGLTexture, the GrGLTexture
creates a new GrGLTextureParameters and any GrBackendTextures created
from that GrGLTexture will share ownership.
Clients indicate parameter changes by calling
GrBackendTexture::glTextureParametersModified().
We still assume all texture parameters may have changed after a call
to GrContext::resetContext() (for now). The "timestamp" that is used
to implement this has been moved from GrGpu to GrGLGpu as there were
no other use cases.

There is some logic in here for 2.0 as well, just as a

This seems to resolve the bug where some GPUs weren't
advertising correctly that they had vertex array object
support, by checking for both extension names (with and
without "GL_" prefix)
Of note, this saves about 18 Kb (5.5 Kb gzipped) of code size

This replaces most (all?) of the cases where it was

For consistency, I tried to check first for GL, then for
GLES, which involved re-arranging a few if blocks.
