Remove memory category from chrome://tracing

The tcmalloc heap profiler will be replaced with the heap profiler
in memory-infra. This removes the old "memory" category in
chrome://tracing. (For now, the checkbox still exists in the UI.)

A few places still reference the heap profiling functionality of
tcmalloc. This is left untouched.
