perf arm_spe: Separate setting of memory levels for loads and stores
For a load hit, the lowest-level cache reflects the latency of fetching
a data. Otherwise, the highest-level cache involved in refilling
indicates the overhead caused by a load.
Store operations remain unchanged to keep the descending order when
iterating through cache levels.
Split into two functions: one is for setting memory levels for loads and
another for stores.
