patch 9.0.1780: Vim9 type not defined during object creation

Browse Source 
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.
