gallium: Change PIPE_CAP_TGSI_FS_FBFETCH bool to PIPE_CAP_FBFETCH count
TGSI's FBFETCH instruction currently only supports reading from a single
render target, but NIR intrinsics can support multiple render targets.
radeonsi can only support fetching from RT 0, but other drivers may be
able to support fetching from any render target.
To express this, this patch renames PIPE_CAP_TGSI_FS_FBFETCH to simply
PIPE_CAP_FBFETCH, and converts it from a boolean "is FBFETCH supported?"
to an integer number of render targets which can be fetched.

iris: Record state sizes for INTEL_DEBUG=bat decoding.
Felix noticed a crash when using INTEL_DEBUG=bat decoding. It turned
out that we were sometimes placing variable length data near the end
of a buffer, and with the decoder guessing random lengths rather than
having an actual count, it was walking off the end and crashing. So
this does more than improve the decoder output.
Unfortunately, this is a bit more complicated than i965's handling,
because we don't have a single state buffer. Various places upload
data via u_upload_mgr, and so there isn't a central place to record
the size. We don't need to catch every single place, however, since
it's only important to record variable length packets (like viewports
and binding tables).
State data also lives arbitrarily long, rather than being discarded on
every batch like i965, so we don't know when to clear out old entries
either. (We also don't have a callback when an upload buffer is
released.) So, this tracking may space leak over time. That's probably
okay though, as this is only a debugging feature and it's a slow leak.
We may also get lucky and overwrite existing entries as we reuse BOs,
though I find this unlikely to happen.
The fact that the decoder works in terms of offsets from a state base
address is also not ideal, as dynamic state base address and surface
state base address differ for iris. However, because dynamic state
addresses start from the top of a 4GB region, and binding tables start
from addresses [0, 64K), it's highly unlikely that we'll get overlap.
We can always improve this, but for now it's better than what we had.

This new lowering pass implements the OpenGL ES blend pipeline in
shaders, applicable to hardware lacking full-featured blending hardware
(including Midgard/Bifrost and vc4). This pass is run on a fragment
shader, rewriting the store to a blended version, loading in the
framebuffer destination color and constant color via intrinsics as
necessary. This pass is sufficient for OpenGL ES 2.0 and is verified to
pass dEQP's blend tests. MIN/MAX modes are included and tested as well.
That said, at present it has the following limitations:
- MRT is not supported (ES3).
- sRGB support is missing (ES3).
- Extended blending is not yet ported from GLSL IR lowering (ES3.2)
- Dual-source blending is not supported. (N/A)
- Logic ops are not supported. (N/A)
v2: Fix code conventions (per Ian Romanick's feedback). Implement color
masks.
This pass should be in common nir/ space, but due to non-technical
reasons, for now it's in Panfrost space. In the future, depending if
other drivers need some of the functionality, we can move this back to

vulkan/wsi: Set X11 minImageCount to 3.
For IMMEDIATE and FIFO, most games work in a pipelined manner where the
can produce frames at a rate of 1/MAX(CPU duration, GPU duration), but
the render latency is CPU duration + GPU duration.
This means that with scanout from pageflipping we need 3 frames to run
full speed:
1) CPU rendering work
2) GPU rendering work
3) scanout
Once we have a nonblocking acquire that returns a semaphore we can merge
1 and 3. Hence the ideal implementation needs only 2 images, but games
cannot tellwe currently do not have an ideal implementation and that
hence they need to allocate 3 images. So let us do it for them.
This is a tradeoff as it uses more memory than needed for non-fullscreen
