patch 9.0.1741: No type checking in interfaces
Problem: No type checking in interfaces
Solution: Implement member type check in vim9 interfaces
Most of the code is a small refactoring to allow the use of a where_T
for signaling the type mismatch, the type checking itself is pretty
simple.
Improve where_T error reports
Let the caller explicitly define the kind of location it's referring to
and free the WT_ARGUMENT enum from its catch-all role.
Implement type checking for interface methods
Follows closely the logic used for type-checking the members.
