Modify ALLOW_UNUSED to allow enabling unused local warnings on MSVC.
This splits the macro into two:
int a = 1;
ALLOW_UNUSED_LOCAL(a);
and
typedef Foo Bar ALLOW_UNUSED_TYPE;
void foo() ALLOW_UNUSED_TYPE; // ALLOW_UNUSED_TYPE_OR_FUNC seemed too verbose
This matches changes that have already been made in Blink.
