  Log Message:
  -----------
  [libc][stdlib] Make the FreeListHeap constant-initializable (#95453)

This refactors some of the FreeListHeap, FreeList, and Block classes to
have constexpr ctors so we can constinit a global allocator that does
not require running some global function or global ctor to initialize.
This is needed to prevent worrying about initialization order and any
other module-ctor can invoke malloc without worry.
