The json file now only contains the feature display name.  The variable
name is automaticaly derived.

For consistence with Chromium and other Chromium-based projects, the
display name is now always snake_case, and that's what's specified in
the json files.  This also makes camelCase variable name generation
trivial (as opposed to the other way around).

Feature overrides now accept both snake_case and camelCase names to
ensure compatibility with existing scripts.  This is done by removing _
and comparing override names with feature names in lower case.

In the fix for chromium:1299211, we added a new pool in the RendererVk
and pick which pool to use at the getDefaultBufferPool() call. This CL
fixes the original problem differently. In this CL we still uses the
ShareGroup's pool. When display global texture is enabled, we orphan the
non-empty buffer blocks into renderer and check and destroyed from
garbage collection code. This way we still only deal with one buffer
pool and all logic is mostly in context destroy code path, which I
believe is a better solution.

Use the total number of pixel shader outputs as the base

making the vertex shader depend on the number of draw-time pixel shader
outputs.

Add a test that exercises SSBOs in vertex shaders, varying the number of
draw-time pixel shader outputs (which should have no effect on register
