Issue 50992 - Bump jemalloc version and enable profiling

Description:
jemalloc 5.2.1 release introduced a number of fixes.
https://github.com/jemalloc/jemalloc/releases/tag/5.2.1

Additionally:
* Override default page and hugepage sizes, because builder machines may not match the target systems.
* Enable profiling by default (--enable-perf), so it can be used for troubleshooting.
