Problem: Vim9 missing access-checks for private vars
Solution: Use the proper check for private/readonly variable. Access
level for a member cannot be changed in a class implementing an
interface. Update the code indentation

Problem: Vim9: need instanceof() function

Implemented in the same form as Python's isinstance because it allows
for checking multiple class types at the same time.

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.

Problem: wrong error messages when passing wrong types to count()
Solution: fix it
This fixes two problems:
1. When passing wrong type to {ic} argument of count(), two error
messages are given, the second of which is misleading.
2. When passing wrong type to {comp} argument of count(), the error
message doesn't mention that {comp} may be a String.

Problem: Class "implements" argument not implemented.
Solution: Implement "implements" argument. Add basic checks for when a
class implements an interface.
Problem: Can add text property with negative ID before virtual text
property.
Solution: Remember that a text property with a negative ID was used and give
an appropriate error message. (closes#11725)
Fix index computation.
Problem: Code for making 'shortmess' temporarily empty is repeated.
Solution: Add functions for making 'shortmess' empty and restoring it.
(Christian Brabandt, closes#11709)
Problem: Object member can't get type from initializer.
Solution: If there is no type specified try to use the type of the
initializer. Check for a valid type.
Problem: Classes are not documented or implemented yet.
Solution: Make the first steps at documenting Vim9 objects, classes and
interfaces. Make initial choices for the syntax. Add a skeleton
implementation. Add "public" and "this" in the command table.
