[Typing] mypy complains if we pass a custom type to `bloq.call_classically()`

[tanujkhattar]

We've recently added QGF and QGFPoly classes to the quantum data types. As a result, we want to pass instances of custom types (eg: galois.Poly) as parameters to bloq.call_classically() method. On doing this, mypy complains with a arg-type error since definition of ClassicalValT is restrictive.

For now, I'm adding # type: ignore[arg-type] to unblock development, but someone should go and fix this. For example, see tests in #1622

what does the solution look like? Do you want all possibilities enumerated within ClassicalValT? should we remove the annotation or make ClassicalValT into Any?
