ClassDB does not handle virtual methods completely

[RedMser]

Godot version

4.0 alpha 16

System information

Windows 10

Issue description

Not all methods of ClassDB seem to know how to handle virtual methods. See code below for examples on which work and which don't:

Steps to reproduce

print(ClassDB.class_get_method_list(&"Node")) # contains _process among other methods, like expected
print(ClassDB.class_has_method(&"Node", &"_process")) # returns false, this is a bug!
# I have not tried ClassDB::get_method since it has no gdscript bindings, but in the C++ code it looks like it does not handle virtual methods either...

This is for the most part by design, although its quite weird. In the Godot ClassDB API, there is a rule where virtual methods can't be called externally, only overriden by classes inheriting it, so as they can't be called they only appear in the listing, but you can't really access them in any way.

This probably should be documented somewhere, I guess, but its not a bug.
