Update the ANGLE test GL context, GrContextFactory, and config parsing to allow explicit control of ANGLE front/backend.
This will allow us to explicitly test ES2 vs ES3 interfaces to ANGLE as well as D3D9, D3D11, and OpenGL backends.
Also makes the angle api types valid in all builds (but will just fail when SK_ANGLE=1 or not on windows for the d3d backends).

Use DEF_GPUTEST_FOR_*_CONTEXT macros to obtain the
test GPU context.
Makes changing the context -related classes easier,
since not all tests need to be changed.

I have been hacking at this test trying to understand why the N5 is
still sometimes crashy (it seems, less but not zero now). No luck so far.
But, while I've been reading and hacking at it, I think I've made a
few small improvements, mostly to readability.

This is a speculative fix for the crashing N5 bots. It looks like the bots are
always failing in or around FloatingPointTextureTest.
It looks like sometimes they're hitting a SIGBUS, which I suspect is stack
overflow. FloatingPointTextureTest allocates ~320K on the stack, which may
be too much. This CL moves those buffers to the heap. For consistency I did
the same with the half-float tests, though they're only using ~1/8th the stack.
It looks like sometimes the bots are failing to malloc. I don't understand that,
and this CL doesn't address that directly. But it's possible this is still a stack
overflow, just trashing RAM and causing arbitrary mayhem instead of a SIGBUS.
I have no idea why this is a problem only on the N5. I have been unable to
reproduce this locally, neither with a K N5 nor an L N5, but the bots are pretty
reliable.

Added in check for sized internal format.
Made choice between RED and ALPHA orthogonal to HALF_FLOAT and
HALF_FLOAT_OES.
Enabled rendertarget support on ES 2.0.

It's unclear what params should be used for half float alpha
rendertargets, so they are disabled for the moment.

This allows us to create distance field textures with better precision,
which may help text quality.

Consolidate read/write funcs in context.
Remove support for reading pixels from a surface that's not a target. It's currently broken and neither used nor tested.
