Stop creating CodecSrcs with unused scale

Only JPEG and WEBP support native scaling, so only create a CodecSrc
with a scale for those types.

If I run

    dm --src image --images resources

this cuts down the number of Srcs from 11063 to 8032. All of these
trimmed Srcs would have failed quickly for each Sink (3 Sinks with the
above flags), but this will avoid creating them.

It drops the runtime on my mac from 13.2s to 11.4s, for about a 14%
speedup.

If there are no issues, this version will be released May 26.

Let's start testing with it, so we are ready to update Chrome when
it is available.

Ensure that SkColorTable->fCount is set properly after decodes

We now have some blits that will process the color table.

If we erroneously report that the size of the color table is 256,
we will do extra work and annoy MSAN.

Remove workarounds initializing command buffer EGL

The eglDisplay() of command buffer EGL implementation now does not
allocate a new EGL display per call, rather just returns the global.

The EGL implementation is fixed as part of bug 581634.

Removes eglTerminate call, as it's should not be used in Skia at the
moment. The call will terminate all of EGL, which is not intendend. The
previous usage was only due to incorrect implementation of the API.  Not
added back to anywhere else, leaking EGL globals is as
designed. Discussed in https://chromiumcodereview.appspot.com/1733323002.

Support allowSRGBInputs on Vulkan (via secondary texture views)

All textures still have a "correct" image view that matches their actual
format. For sRGB textures, we can ask for a non-sRGB view that is
created on demand (and cached), in legacy mode.

Finally, turn on sRGB support in Vulkan. The gamma GM now looks correct
in both L32 and S32.
