valgrind: Add --support-valgrind configure option
When --enable-valgrind is passed, PCRE will annotate some memory regions
as unaddressable, aiding in finding invalid memory accesses when running
under valgrind. This is useful mostly for debugging PCRE itself, and thus
probably should not be enabled in release builds.
