Remove allocation in parse_identifier

[MichaReiser]

Summary

I think this PR removes an allocation from parse_identifier.

parse_identifier converts the Box<str> from the TokenValue::Name to a String by calling .to_string.
to_string is a small wrapper around format!("{name}") which allocates a new string without reusing the Box<str> allocation, unless the compiler can see through the operation.

This PR uses Box<str>::into_string which, to my knowledge, reuses the underlying allocation.

I'll go ahead and merge this. This change should be pretty uncontroversial 😆
