Emulate legacy LUMINANCE / ALPHA pixel formats in TexStorage

Project Member Reported by sunn...@chromium.org, Feb 9 2018 
Command buffer implements emulation (swizzle) for LUMINANCE/ALPHA legacy pixel formats (UNSIGNED_BYTE only not half-float/float) with TexImage but not with TexStorage. WebGL 2 exposes TexStorage and also supports these legacy formats but this is not tested.

Related to issue 810591 where we discovered that LUMINANCE_16F is not supported with TexStorage on mac.

That CL did implement luminance alpha emulation for TexStorage with unit tests. I guess the other half of this bug is to implement webgl2 conformance tests.

zmo@ you implemented conformance tests so we can close this now?

jdarpinian@: since you are working on luminance alpha stuff, can you take this task?

Sure, I can look at it.
