allocate a fresh meta page and add it to the global list.

Claim an aligned address range for huge pages

free every huge page in a range individually (as we allocated per page) note: needed with VirtualAlloc but could potentially be done in one go on mmap

Primitive aligned allocation from the OS. This function guarantees the allocated memory is aligned.

Note: the `try_alignment` is just a hint and the returned pointer is not guaranteed to be aligned. Also `hint_addr` is a hint and may be ignored.

returns `true` if after collection `mi_page_immediate_available` is true.

Get a fresh page to use

Find a page with free blocks of `page->block_size`.

Collect the local `thread_free` list using an atomic exchange.

Bytes available in a block

Called when the process is done (cdecl as it is used with `at_exit` on some platforms)

Initialize the process; called by thread_init or the process loader

Set up handlers so `mi_thread_done` is called automatically
