* Add set conversion helper for generic_oidc predicate expressions

This adds a small enhanced version of `set()` for generic_oidc that
can convert lists to sets.

This is needed because almost all interesting functions in the
predicate language operate on sets, not lists. So, when given `[]any`
parsed from JSON claims, they fail. This limitation affects:
- `contains()`, `contains_any()`, `contains_all()`
- `regexp.match()`
- `is_empty()`
- ...and every other function that claims to operate on `[]string`
  according to the public docs but actually operates on sets.

I just created a tiny override that defers to a new
`expression.NewFlattenedSet()` constructor. It lets us (or others)
easily override the built-in `set()` impl that only accepts variadic
`string...` with this better variant, without potentially causing
unexpected changes that might, for example, cause expressions to
allow access that were previously broken due to this limitation.

* Fix failing test

* Fix imports

* Use bool as parser's generic param instead of any

Removes an unnecessary cast.
