Everything here is closely based on the approach taken for explicit_bzero. This includes the bits that relate to internal uses of explicit_bzero within glibc (although we don't currently have any such internal uses of memset_explicit), and also includes the nonnull attribute (when we move to nonnull_if_nonzero for various functions following C2y, this function should be included in that change). The function is declared both for __USE_MISC and for __GLIBC_USE (ISOC23) (so by default not just for compilers defaulting to C23 mode). Tested for x86_64 and x86.
