  [mlir][OpFormatGen] Add support for anchoring optional groups with types

This revision adds support for using either operand or result types to anchor an optional group. It also removes the arbitrary restriction that type directives must refer to variables in the same group, which is overly limiting for a declarative format syntax.

Fixes PR#48784
