perf arm_spe: Improve SIMD flags setting

perf arm_spe: Improve SIMD flags setting

Fill in ASE and SME operations for the SIMD arch field.

Also set the predicate flags for SVE and SME, but differences between
them: SME does not have a predicate flag, so the setting is based on
events. SVE provides a predicate flag to indicate whether the predicate
is disabled, which allows it to be distinguished into four cases: full
predicates, empty predicates, fully predicated, and disabled predicates.

After:
