Remove calls to AllocationLocationTracker for native memory
Remove calls to AllocationLocationTracker for native memory

Summary:
`getStackTracesTreeNodeForAlloc` only works for memory that was tracked with `newAlloc`.
For now, that is only memory that goes through GC APIs.

Various places were calling this function on native memory which was allocated
with `malloc`, not GC memory. This led to SIGSEGV on nullptr when trying to take heap profiles
of these objects.

`newAlloc` could, in theory, work with native memory as well. But building out support for that
is outside the scope of this fix.
