Add CONST_FLAG_UNSIZED

Browse source 
In order to support unsized constants being used as parameters, the `const` struct needs to know if it is unsized (so that the parameter can be used to set the size).
Add unsized flag to param value serialization and rtlil back-/front-end.
Add cell params to `tests/rtlil/everything.v`.
