This isn't ideal, nor is it required for all descriptor types, but will
work for the time being.

On cores without gs_rta_support, PBE resolves might depend on writes
that occur within the deferred RTA clears that happen after the PBE
has written.
Since the driver can't know at renderpass creation whether RTA clears
are needed, PBE resolves must be disabled.

Deferred clears are a way to turn clear operations into transfer operations.
One use of them is to account for multi-layer clears when the HW doesn't
support render targets array.

The maximum width of a texstate is 16k-1; use the highest power of two
(8k) as a fixed width and only adjust the height by the view size.

With the currrent state of things when setting up the texture state
word we need to make sure the swizzle is obtained from a format
compatible with the TPU.

When sharing scratch buffers across framebuffers, it reallocates the scratch
buffer to ensure the smallest scratch buffer is always in use. However, the
check to do this meant that it was possible to end up with a scratch buffer that
was too small, leading to page faults or memory corruption.

The starting offset is always `0` and there isn't really a reason
for why it should be non-zero, we always want to DMA into the
shareds from the beginning, for the load_ops, so removing it.

To clear up the ambiguity of uncompressed/compressed formats:
- Always use the correct enum type to refer to them, and
- Split the border colour table into two halves so the compressed tex
format enum can be used as an index directly without applying an
offset.

Devices with the feature tpu_border_colour_enhanced don't require
e5b9g9r9 formats to be encoded and instead read the channels directly
as f16 values. Without this special handling, two channels were left
uninitialised, leading to random test failures.
