[libc] Move LLVM_LIBC_IS_DEFINED macro to its own header (#190081) ...

This moves the LLVM_LIBC_IS_DEFINED macro to its own header is
__support/macros.  Its implementation leverages cpp::string_view
instead of rolling its own strcmp; this necessitated fixing
several missing constexpr in the string_view implementation.

The new __support/macros/macro-utils.h is also broken out to hold
the stringification macro and can be used in future for token
pasting shenanigans and other such generic macro machinery.
