[Twig] Add goto for global variables defined in YAML

[King2500]

config.yml:

twig:
    globals:
        my_var: 'Hello World'

Problem:
Goto (Ctrl+Click) in Twig templates is not working:

{{ my_var }}

[COil]

Do not know if it can be done, as my_var may be created by any Twig extension, not only in this twig parameter section.
