Auto merge of #14878 - lowr:feat/metavar-expr-count, r=Veykril
Implement `${count()}` metavariable expression
This PR implements `${count()}` metavariable expression for MBE as described in [RFC 3086][rfc]. See [this section][sec-count] of the RFC for its semantics.
Additionally, this PR changes the type of depth parameter of `${index()}` from u32 to usize so as to match how [rustc parses it][index-usize].
Part of #11952
Fixes #14871
