Problem: Vim9: problem calling class method from other class
Solution: Fix this problem, fix readonly object access, update error
messages.
Calling a class method from another method without the class name prefix
doesn't work properly.
A readonly object variable is modifiable outside the class using a
nested object assignment.
Remove the unused E1338 error message.
Update error messages.

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.
