Initialize rpmalloc in Mem{Alloc,Free}Callstack().

Browse Source 
rpmalloc may still be uninitialized here (i.e. if memory allocation/free
is performed before any other tracy operation that would initialize
thread_local data). Since memory allocations are using serialized queue
(which is not held in thread_local section) and obtaining callstack
involves memory allocation, we need to initialize rpmalloc manually.

This won't be a problem when support for zone callbacks becomes online,
because zones are stored in per-thread queues, which initialize
thread_local data before rpmalloc is needed in the Callstack() call.
