Robert Clausecker 6c57e368eb lib/libc: implement C23 memalignment() 
This new function computes the alignment of a pointer.
It is part of ISO/IEC 9899:2024, the new C standard.
If the pointer is a null pointer, null is returned.
I have tried to write an implementation that can cope
with traditional address-based architectures, even if
size_t and uintptr_t are of different length.  Adjustments
may be needed for CHERI though.

A man page is provided, too.  No unit test for now.
