Add masked_scan_uint32_peek

That is, extend masked_scan_uint32 to not only returned the offset where a
match was found (if any), but also the uint32 that matched at that location, as
it is available for free anyway.

It is fairly typical to scan for some marker/pattern and then need some other
byte(s) that are pretty much nearby, which can then be obtained immediately
this way, without having to go through _copy.
