Remove cql3::functions::function_call::raw and replace it with cql3::expr::function_call, which already existed from the selector migration to expressions. The virtual functions implementing term::raw are made free functions and remain in place, to ease migration and review. Note that preparing becomes a more complicated as it needs to account for anonymous functions, which were not representable in the previous structure (and still cannot be created by the parser for the term::raw path). The parser now wraps all its arguments with the term::raw->expr bridge, since that's what expr::function_call expects, and in turn wraps the function call with an expr->term::raw bridge, since that's what the rest of the parser expects. These will disappear when the migration completes.
