This is needed for bgr* textures backed by eglimages that traditionally
used glTextureView() to mediate colorspace conversions, as that approach
has been determined to cause format misinterpretation issues.
This commit simply adds the capabilty but doesn't enable such manual
encode/decode for any uses yet.

In those cases, we need to go through the same path as we already do for
GL_TEXTURE_CUBE_MAP.

Since externally-stored BGRA resource buffers must remain with
BGRA byte ordering, there are several special cases in the custom
blitter that need to be handled, based on the source and destination
resource formats, as well as the views requested on each by the caller.
This change gives the caller more control over the swizzling operation
to perform during the shader-based blit, so the caller can reconcile the
special cases more concisely.

BGRA emulation was added to address rendering artifacts when GL guest
apps are run on a GLES host with virglrenderer's use_gles == true.
Due to tenuous compatibility of EXT_texture_format_BGRA8888 with
gamma correction (sRGB formats/views) and multisampled rendering on
GLES hosts, it is best to represent BGR* resourcs with RGB* internal
format and add necessary byte re-ordering on to/from transfers instead.
Note, however, that removing the existing BGR* emulation will cause
problems for externally stored resources such as EGL images, and GBM
allocated buffers, which may actually be stored with BGR* byte-order.
This is addressed in the commits immediately following this one.

On GL 4.4 (and GLES with EXT_sRGB_write_control) blits will decode and
encode sRGB when GL_FRAMEBUFFER_SRGB is supported, and they don't decode
when it isn't supported. Enabling or disabling this is signalled from
the guest by using the according surfaces.
In summary, there is no need to use the GL fallback for a blit decoding
sRGB, because this can also be handled in a normal blit.
