This PR implements parser support for associated return type bounds:
T: Foo<bar(): Send>. This PR does not implement associated return types (T::bar(): Send) because it's not implemented even in rustc, and also removes(..)-style return type notation because it has been removed in rust-lang/rust#110203 (effectively reverting #14465).I don't plan to proactively follow this unstable feature unless an RFC is accepted and my main motivation here is to remove no-longer-valid syntax
(..)from our parser, nevertheless adding minimal parser support so anyone interested (as can be seen in #14465) can experiment it without rust-analyzer's syntax errors.
