SPM is hardware feature that allows us to dump performance counters
at a sampling interval to a buffer. It is used by RGP to report cache
counters.

Add the number of SPM wires because sometimes a block has eg.
2 counters but only holds 3 16-bit counters instead of 4.

Instead of having different layouts which might complicate things when
some registers are missing, hardcode the SELECT and SELECT1 registers
into separate arrays.
The SELECT registers are "legacy" counters, while the SELECT1 registers
are SPM counters.
This is more verbose and emit more UCONFIG registers, but emitting the
SELECT registers is now much simpler and it seems less error prone.
This will also help emitting the SPM configuration.

This seems unnecessary if the first select register is correctly set.
This CB filter was always disabled anyways.

Performance counters will be used by RADV for VK_KHR_performance_query
and also for adding SPM support.
