provider: has("python3_dynamic") et al. #10980

Browse Source 
Vim added more flags for testing yet more dimensions of its Python
situation.  Handle those in eval_has_provider().

vim-patch:8.0.1436: not enough information about what Python version may work
Problem:    Not enough information about what Python version may work.
Solution:   Add "python_compiled", "python3_compiled", "python_dynamic" and
            "python3_dynamic" values for has().
