pan_drm.c was only meaningful when we were supporting 2 kernel drivers
(mali_kbase, and the drm one). Now that there's now kernel-driver
abstraction we're better off moving those functions were they belong:
* BO related functions in pan_bo.c
* fence related functions + query_gpu_version() in pan_screen.c
* submit related functions in pan_job.c
While at it, we rename the functions according to the place they're
being moved to.

The compiler now sets the "Null Render Target" bit in the RT write
extended message descriptor, causing it to write to an implicit null
surface without us needing to set one up in the binding table.
Together with the last patch, this improves performance in Car Chase on
an Icelake 8x8 (locked to 700Mhz) by 0.0445526% +/- 0.0132736% (n=832).

When there are no color regions (i.e. a depth only pass), we can set
the "Null Render Target" bit in the Gen11 RT write extended message
descriptor to indicate that it should behave as if it's writing to a
null render target, without the need for a binding table entry.
This lets drivers avoid setting up that null RT binding table entry,
but more importantly means the HW doesn't actually have to bother
looking up the surface state.
Together with the next patch, this improves performance in Car Chase on
an Icelake 8x8 (locked to 700Mhz) by 0.0445526% +/- 0.0132736% (n=832).

Before this commit, we had only FPRoundingMode decoration (the per
instruction one) that is applied during the SPIR-V handling. In
vtn_alu we find out the rounding mode, and generate the code
accordingly that later will be used to look for the respective
nir_op_f2f16_{rtz,rtne}.
Per-instruction gets prioritized because we make them explicit
conversions (with RTZ or RTNE nir opcodes) and they will override the
default execution mode defined with float controls. However, we need
to come back to the mode defined by float controls after the execution
of the FP Rounding instruction.
Therefore, the new SHADER_OPCODE_FLOAT_CONTROL_MODE opcode will be
used to set the default rounding mode and denorms treatment in the
whole shader while the pre-existent SHADER_OPCODE_RND_MODE, will be
used as prioritized rounding mode in a per-instruction basis.
