Format code and add static checks (#599)

* gdformat .

* Lint code - Part 1

* Format code - Part 2

* Lint code - Part 2

Trying to fix the max allowed line length errors

* Add normal_map_invert_y to the image .import files

Because of Godot 3.4

* Do not call private methods outside of the script's scope

Lint code - Part 3

* Format code - Part 3

* Fixed more line length exceeded errors - Lint code Part 3

* Export array of licenses - Lint code part 4

* Clean hint_tooltip code from Global

Removes a lot of lines of code

* Create static-checks.yml

* Fix FreeType's license
