malloc: Improve performance of __libc_calloc
Improve performance of __libc_calloc by splitting it into 2 parts: first handle
the tcache fastpath, then do the rest in a separate tailcalled function.
This results in significant performance gains since __libc_calloc doesn't need
to setup a frame.
On Neoverse V2, bench-calloc-simple improves by 5.0% overall.
Bench-calloc-thread 1 improves by 24%.
