[X86] Remove TuningPOPCNTFalseDeps from AlderLake (#154004)
This false dependency issue was fixed in CannonLake looking at the data
from uops.info. This is confirmed not to be an issue based on
benchmarking data in #153983. Setting this can potentially lead to extra
xor instructions whihc could consume extra frontend/renaming resources.
None of the other CPUs that have had this fixed have the tuning flag.
Fixes #153983.
