GDScript: Refactor builtin functions

They are now called "utility functions" to avoid confusion with methods
of builtin types, and be consistent with the naming in Variant.

Core utility functions are now available in GDScript. The ones missing
in core are added specifically to GDScript as helpers for convenience.

Some functions were remove when there are better ways to do, reducing
redundancy and cleaning up the global scope.
