configure.ac: check for -Wshadow-local and -Wshadow-compatible-local

Summary:
Add a configure-time check for whether -Wshadow-local and
-Wshadow-compatible-local are supported.  If so, arrange to
define HAVE_SHADOW_LOCAL_WARNINGS.

In Portability.h, use that new symbol to choose whether
to define FOLLY_GCC_DISABLE_NEW_SHADOW_WARNINGS, which
used pragmas to disable those new warnings.
