perf auxtrace: Add auxtrace_cache__remove()
Add auxtrace_cache__remove(). Intel PT uses an auxtrace_cache to store
the results of code-walking, so that the same block of instructions does
not have to be decoded repeatedly. However, when there are text poke
events, the associated cache entries need to be removed.
