[PATCH v3 08/25] perf arm_spe: Consolidate operation types
From: Leo Yan <leo.yan@arm.com>

Consolidate operation types in a way:
(a) Extract the second-level types into separate enums.
(b) The second-level types for memory and SIMD operations are classified
by modules. E.g., an operation may relate to general register,
SIMD/FP, SVE, etc.
(c) The associated information tells details. E.g., an operation is
load or store, whether it is atomic operation, etc.
Start the enum items for the second-level types from 8 to accommodate
more entries within a 32-bit integer.
