Add MissingParamType for form, form_state and form_id

Reviewed the changes and the typehints line up with the variables being updated.

LGTM

One $form_id is typed as array instead of string

@mstrelan, thanks.

Feedback appears to be addressed.

Committed/pushed to 11.x and cherry-picked back through to 10.3.x, thanks!
