[x86] Intel scheduler models' instruction MicroOps counts need to consistently use the fused domain

[RKSimon]

The microops counts need to be compatible with ROB / MicroOpBufferSize - while the pipe resource counts need to match unfused uop numbers to correctly model pipe occupancy.

The PFM uop counters might need checking to ensure they match the retire_slots counts (the "any"/"all" counts are the unfused domain counts).
