Replace SDL's memory allocation functions with a custom set.
It is not safe to call this function once any allocations have been made,
as future calls to SDL_free will use the new allocator, even if they came
from an SDL_malloc made with the old one!
If used, usually this needs to be the first call made into the SDL library,
if not the very first thing done at program startup time.
\param malloc_func custom malloc function.
\param calloc_func custom calloc function.
\param realloc_func custom realloc function.
\param free_func custom free function.
\returns true on success or false on failure; call SDL_GetError() for more
information.
\threadsafety It is safe to call this function from any thread, but one
should not replace the memory functions once any allocations
are made!
\since This function is available since SDL 3.2.0.
