Similar to util_format_get_component_bits, get the bit offset for a
particular channel in a given format.
Use this to calculate the shift/mask sets for formats when creating DRI
configs, as a prelude to ripping out and replacing the hardcoded table.

These actually match the Vulkan format enums for single-plane YCbCr
formats, unlike the other PIPE_FORMAT_* enums which put luminance in the
red channel.

Without this, gallivm doesn't know what to do with the result data of a
texture fetch. We have a bunch of gallivm code to handle these but, as
far as I can tell, none of it works properly without channel types. The
YUYV texturing helpers all consume a 32-bit packed value, unpack it,
shuffle things as needed, and then re-pack into a 32-bit RGBA value,
trusting later code to unpack that as 8-bit UNORM. For the raw formats,
this unpacking never happens.
What saves us is that I also don't think any of this code is ever used.
LLVMpipe supports the actual YUYV formats and we don't use the gallium
lowering pass which lowers to the raw formats.

When NV21 lowering with hardware sampling and shader CSC was added, the
incorrect PIPE_FORMAT_G8_B8R8_UNORM was used. That format is supposed to
represent vulkan NV12 instead.
This commit introduces PIPE_FORMAT_R8_B8G8_UNORM, which correctly describes the
gallium mapping for YUV CSC, with R as Y, instead of G as Y.

YV12 is the same as DRM_FORMAT_YVU420.
We lower it to PIPE_FORMAT_R8_B8_G8_420, which is equivalent to
PIPE_FORMAT_R8_G8_B8_420 with U/V planes swapped.
This is used for hardware that can sample from YUV but need CSC in shader.

This new format is similar to PIPE_FORMAT_G8_B8_R8_420, but with R as Y, G as U
and B as V. The need for two diferent formats here is because gallium maps the
YUV channels differently from vulkan.
Some hardware, e.g. Mali GPUs, can sample from I420 but need CSC in shader,
this patch implements that.

util_clear_texture implements clear_texture through a memset.
This patch implements u_default_clear_texture, which tries to clear the
given texture using a surface plus clear_render_target or
clear_depth_stencil.
In case this path fails, either because the formats are non-renderable
or for some other reason, we fallback to `util_clear_texture`, which is
guaranteed to work.
This will allow us to make ARB_clear_texture available to every driver,
as well as provide HW acceleration for the clear_texture operation.
If some hardware doesn't want to use it, such as llvmpipe, it can always
just directly point to the software version using pipe->clear_texture.
