[libc] implement endian related macros ( #126368 )
...
Follow up of #125168 .
This patch adds endian-related macros to `endian.h`. We utilize compiler
built-ins for byte swap functions, which are already included in our
minimal supported compiler version.

[libc] Add the <endian.h> header. ( #125168 )
...
Closes [#124631 ](https://github.com/llvm/llvm-project/issues/124631 ).
ref:
https://pubs.opengroup.org/onlinepubs/9799919799/basedefs/endian.h.html
This patch adds the implementation of `endian.h`, which includes the
header itself and three related macros. These macros in the header rely
on the compiler preprocessor, similar to how
https://github.com/llvm/llvm-project/blob/main/libc/src/__support/endian_internal.h
does. Hopefully this will meet the requirements for compiling llvm with
llvm-libc.
