refactor(lexer): compile Lanes::clear separately for each CPU feature set (#28643)

Part of effort to move to runtime CPU feature detection.

Apply `cpu_versions!` to `Lanes::clear`. It doesn't use `cpu` yet. Its only caller `lex_raw_impl` passes `cpu`.

Codegen: no change in any build. `Lanes::clear` was already inlined into `lex_raw_impl`, and still is.
