The PE renders RB_SWAP formats (e.g. R8G8B8A8_UNORM) using the A8R8G8B8
hardware format, which stores data in BGRA byte order internally. For
shared/dmabuf resources, external consumers expect the byte order
mandated by the DRM FourCC.
Hook into flush_resource to apply an R<->B swap during the existing
shadow-to-base copy, using the BLT dest swizzle or RS SWAP_RB.

The rb-swap rework (commit a5766e75e48) uses A8R8G8B8 as the texture
format for RB_SWAP pipe formats and performs R<->B conversion during
transfer blits. This breaks dmabuf import/export: external producers
write RGBA bytes, but A8R8G8B8 interprets them as BGRA; transfer blits
incorrectly swap R<->B on data already in the correct byte order.
For shared/imported resources, bypass the optimization: use the native
texture format (A8B8G8R8) so the sampler reads RGBA bytes correctly in
both the descriptor and state-based texture paths, skip the R<->B
swizzle in BLT and RS transfer blits since shared resources already
store data in standard byte order, and re-enable the texture shadow
shortcut for shared RB_SWAP resources since the BLT swap is no longer
applied.
Internal-only resources continue using the BGRA-internal optimization
unchanged.

Up to now all push descriptor accesses where going through the binding
table. That's not going to be the case anymore with descriptor buffers
device bindable shaders. Those will do A64 messages to read the
descriptor buffer (for example when build a bounded 64bit address for
storage buffers, or 64bit image format atomic emulation, etc...)
We need to have the offset relative to the push descriptor heap
(internal_state_heap in this case).

The QPU prefetches the next instruction during shader execution.
If the shader assembly size perfectly aligns with a page boundary,
the prefetching mechanism reads past the compiled boundary,
leading to an MMU error.
This commit insert an explicit NOP instruction at the end of the shader
and increases the qpu_inst_count by one when the instruction count
exactly hits a page boundary. This ensures we don't fall off the end
of the last executable instruction page and into invalid memory.
