Token normalization is merged directly into `bump`. Special "unknown macro variable" diagnostic for unexpected `$`s is removed as preventing legal code from compiling.
They are always set synchronously with normalized tokens now

parser: Simplify treatment of macro variables in `Parser::bump` Follow-up to rust-lang#69006. Token normalization for `$ident` and `$lifetime` is merged directly into `bump`. Special "unknown macro variable" diagnostic for unexpected `$`s is removed as preventing legal code from compiling (as a result `bump` also doesn't call itself recursively anymore and can't make `prev_token` inconsistent). r? @Centril
