rust-matchers: make `Matcher` trait object-safe

Before this patch, it is not possible to create a `Matcher` trait-object (like
`Box<dyn Matcher>`), because of the use of a generic parameters in some methods,
namely `impl AsRef<HgPath>`.

While this makes the interface less flexible for callers in theory, it does not
change anything in the current codebase.

Until something like [1] is implemented, this is a "tradeoff" that we need to
make anyway.
