[AMDGPU] Model WMMA co-execution windows in the scheduler for gfx1250

WMMA instructions in gfx1250 exposes an execution window during which
only certain other instruction classes may co-execute. Teach the hazard
recognizer about those windows so the scheduler can fill co-execution slots and
account for the resulting stalls. This adds a preRA hazard recognizer
mode.

Add AMDGPUCoExecInfo.h, a shared model of a co-execution window: the
per-stage capability bitmask, the stage types (CoExecStageType), and
CoExecInfo, which maps a multi-cycle instruction to its per-cycle slot
pattern via getCoExecInfo(). InstructionFlavor and its helpers move here
from AMDGPUCoExecSchedStrategy.h with no functional change so they can
be shared by the scheduler and the hazard recognizer.
