GPencil: Add new parameteres to transform layers

When using grease pencil for drawing Storyboards, it's very common to require a transform of the layers. This transform can be done using the offset modifier, but in some cases, the scene requires a lot of modifiers and makes the file hard to work.

This new feature adds a transforms Location, Rotation and Scale at Layer level, and allows to transform the layer without using a modifier, keeping the scene more clean.

This feature was suggested by @pepeland after receiving feedback from several artists.

Also, done some code cleanup and rename some functions to get a better naming.
