perf vendor events: Update/add grandridge events/metrics

Update events from v1.02 to v1.03.
Add TMA metrics v4.8.

Bring in the event updates v1.03:
https://github.com/intel/perfmon/commit/5ec7a252d0f6ec461f80cc397c9ac25abcd9184f

The TMA 4.8 information was added in:
https://github.com/intel/perfmon/commit/59194d4d90ca50a3fcb2de0d82b9f6fc0c9a5736

New events are:
FP_INST_RETIRED.128B_DP,
FP_INST_RETIRED.128B_SP,
FP_INST_RETIRED.256B_DP,
FP_INST_RETIRED.32B_SP,
FP_INST_RETIRED.64B_DP,
OCR.DEMAND_DATA_RD.L3_HIT.SNOOP_HITM,
