Clang v21+ includes an implementation of P2719 “Type-aware allocation and deallocation functions”.

When compiled with clang v21+, WT code base produces "allocator-wrappers" warnings. E.g.:

src/utilities/util_misc.c:190:1: warning: function util_malloc might be an allocator wrapper [-Wallocator-wrappers]
  190 | util_malloc(size_t len)
      | ^

Currently, these warnings are suppressed (see WT-17010).

Consider adopting type-aware memory allocation instead of suppressing compilation warnings.
