In order to implement a fileset, we'll need owned variants of these matchers. We can of course let callers move Box<dyn Matcher> into these adapters, but we might need to somehow clone Box<dyn Matcher>. So, I simply made adapters generic.
This will be needed to concatenate patterns of different types (such as "prefix/dir" exact:"file/path".) The implementation is basically a copy of IntersectionMatcher, with some logical adjustments. In Mercurial, unionmatcher supports list of matchers as input, but I think binary version is good enough.
