GpuMemoryBufferVideoFramePool: add upload TRACE

GpuMemoryBufferVideoFramePool::CopyVideoFrameToGpuMemoryBuffers schedules
copies to GMBs using a Pool thread, so the upload is sliced and run in
parallel, reconvening after all sub tasks are finished.

This CL adds an ASYNC TRACE to track the duration of the full copy cycle,
encompassing all the parallel (and possibly heterogenous) uploads, to
make it easy to reason about how much time the copy-to-GMBs take.

Support XR30 in GpuMemoryBufferVideoFramePool - Linux

This CL allows XR30 for GpuMemoryBufferVideoFramePool output
format in Linux (not CrOs yet), and teaches GLImageMemory how
to manipulate this format.

Unittests are extended, tested also with high bit depth
videos e.g.:

and media/test/data/...

GpuMemoryBufferVideoFramePool: use BindOnce/OnceCallback

Every git cl upload I get a bunch of presubmits like:

Please consider using base::Bind{Once,Repeating} instead of base::Bind. (crbug.com/714018)

So this CL does the transition: Bind --> BindOnce,
Closure --> OnceClosure, Callback --> OnceCallback, use
of Base::Passed(), in method signatures, we change const &
to moving the argument, and instead Run()ning the Callback
we use std::move(cb).Run().

Threw in a few consts where applicable.  No new code otherwise,
tests (and asan etc) should cover it all.

GpuMemoryBuffer: add image_xb30 capability and RGBX_1010102 BufferFormat

This CL adds a new Gpu FeatureInfo::FeatureFlags and command buffer
Capabilities to signal support for image_xb30, in parallel to the
existing image_xr30. The new flag is used on platforms supporting
glTexImage2D() with data format GL_RGB(A), namely >=gles3, >=gl3.3
or those with the appropriate GL extension.

This CL also adds a new GpuMemoryBuffer format RGBX_1010102 to
be used where image_xb30 is signalled.

With all this, Mac will use image_xr30 <-> BGRX_1010102, and the
GLES3+/GL3.3+ platforms will use image_xb30 <-> RGBX_1010102.

The following revision refers to this bug:

commit 02290321d15a90a00f942444672ac8aed31dd8bc

RELAND: GpuMemoryBuffer: add image_xb30 capability and RGBX_1010102 BufferFormat

The original CL was reverted due to two gl_unittests_ozone failures:
 EGLApiTest.DisabledExtensionBitTest
 EGLApiTest.DisabledExtensionStringTest
these two tests also fail on my soraka ToT, so I think they're just
flaky. The fix is to check for GetSurfaceFactoryOzone() before using
it in HasGLOzone():
http://crrev.com/c/926862/1..3/ui/gl/init/ozone_util.h

TBR=reveman@chromium.org, piman@chromium.org, rsesek@chromium.org, dalecurtis@chomium.org
since the code they reviewed and LGTM'd hasn't changed.

Original CL description ------------------------------------------------

This CL adds a new Gpu FeatureInfo::FeatureFlags and command buffer
Capabilities to signal support for image_xb30, in parallel to the
existing image_xr30. The new flag is used on platforms supporting
glTexImage2D() with data format GL_RGB(A), namely >=gles3, >=gl3.3
or those with the appropriate GL extension.

This CL also adds a new GpuMemoryBuffer format RGBX_1010102 to
be used where image_xb30 is signalled.

With all this, Mac will use image_xr30 <-> BGRX_1010102, and the
GLES3+/GL3.3+ platforms will use image_xb30 <-> RGBX_1010102.

Changing subject to XB30 since that is the format being supported.
In a register XB30 is X2_B10_G10_R10 where R10 is in the low 10 bits.
https://github.com/torvalds/linux/blob/master/include/uapi/drm/drm_fourcc.h#L99

libyuv r1699 supports AB30 which is the alpha version of XB30
Theres also libyuv::AR30ToAB30() if you need to switch back and forth.

c6 (relanded in c8) seems to be sticking and does the trick of using XB30
where present. Closing this bug.
