Problem: Vim9: need instanceof() function
Solution: Implement instanceof() builtin
Implemented in the same form as Python's isinstance because it allows
for checking multiple class types at the same time.

Problem: Vim9 type not defined during object creation
Solution: Define type during object creation and not during class
definition, parse mulit-line member initializers, fix lock
initialization
If type is not specified for a member, set it during object creation
instead of during class definition. Add a runtime type check for the
object member initialization expression
Also, while at it, when copying an object or class, make sure the lock
is correctly initialized.
And finally, parse multi-line member initializers correctly.

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: Calling a base class method through an extended class fails
Solution: Create lookup table for member index in the interface to
to the member class implementing the interface
Create additional tests for Vim9 classes. Fix unconvered memory leaks
and crashes found by the new tests.

Problem: Crash when calling method on super in child constructor. (Israel
Chauca Fuentes)
Solution: Clear the type list. (Ernie Rael, closes#12489, closes#12471)
Problem: Cannot use an object member name as a method argument.
Solution: Do not give an error for using an object member name for a method
argument. (Hirohito Higashi, closes#12241, closes#12225)
Fix line number for other argument error.
Problem: Cannot access a private object member in a lambda defined inside
the class.
Solution: Go up the context stack to find the class. (closes#11866)
Problem: Crash when handling class that extends another class with more
than one object members.
Solution: Correct pointer computations. (closes#11824)
Problem: Class "implements" argument not implemented.
Solution: Implement "implements" argument. Add basic checks for when a
class implements an interface.
Problem: Assignment to non-existing member causes a crash. (Yegappan
Lakshmanan)
Solution: Give an error message and bail out when a member cannot be found.
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.
