On GLES >= 3.1 all the functionality that is currently relevant for
attribute binding in virglrenderer is available. However, GLES 3.1 does
not fully implement GL_ARB_vertex_attrib_binding. Therefore, rename the
flag "have_vertex_attrib_binding" to "have_gles31_vertex_attrib_binding",
and set it when the host implements GL_ARB_vertex_attrib_binding, is
GL >= 4.3 or GLES >= 3.1. As a result with these configuration the new
code path vrend_draw_bind_vertex_binding is used.
Fixes on GLES 3.1 hosts:
dEQP-GLES3.functional.clipping.point.wide_point_z_clip
dEQP-GLES3.functional.clipping.point.wide_point_z_clip_viewport_center
dEQP-GLES3.functional.clipping.point.wide_point_z_clip_viewport_corner
On an Intel Kabylake GLES 3.1 host this also fixes:
dEQP-GLES3.functional.clipping.point.wide_point_clip
dEQP-GLES3.functional.clipping.point.wide_point_clip_viewport_center
dEQP-GLES3.functional.clipping.point.wide_point_clip_viewport_corner
but it should be noted that these three tests expect that also points with a
centre outside the clip volume will be partially drawn when they overlap with
the clip volume because of being "wide" (i.e. when moving towards the clip
volume boundary a wide point would "naturally" move out). The OpenGL standard
defines that points should be clipped the moment the centre is outside the
clip volume (i.e. points will "pop" in and out of the view when moving across
the border). Hence, for a host implementation following the standard to the
letter these tests should actually fail.
v2: - rename have_vertex_attrib_binding to have_gles31_vertex_attrib_binding
- clarify the commit message describing the wide point clipping problem

Commit 84fc54f6bf introduced the use of RG
formats with a swizzle as backing store for guest requested LA formats.
This works for many cases (e.g. blitting), but unfortunately it can't be
used when rendering with blending to an LA target. Since GL doesn't
support texture write swizzles the swizzle needs to happen in the
fragment shader and that's too early for proper blending.
We can safely revert the offending commit since the tests fixed by it
have since been fixed by other commits (e.g., "vrend: Nop sends to
backing iovs for readonly textures v2") in a different way. The one
side effect of reverting is that, depending on the GL version, a less
efficient path may be taken in the guest Mesa when mipmapping LA formats
since they may not be considered color-renderable anymore.
