types: implement Header#ValidateBasic (#4638)

- Move core stateless validation of the Header type to a ValidateBasic method.
- Call header.ValidateBasic during a SignedHeader validation.
- Call header.ValidateBasic during a PhantomValidatorEvidence validation.
- Call header.ValidateBasic during a LunaticValidatorEvidence validation.

lite tests are skipped since the package is deprecated, no need to waste time on it

closes: #4572
