GPencil: Improve gradient stroke thickness

This change tries to improve the control of thickness when mix strength and gradient.

Annotations: Make all 2D editors locked to View

Before, there was a hacky code for Image editor when the image was empty.

Now, all 2D editors are locked to view and when you Move or Zoom, the stroke moves.

This is a fix of T63402.

Still pending if we add more options to 2D editors, but at least now, we have something consistent.

Industry Compat Keymap: Add Sculpt Mode keys

Variable naming, white space fixes.

GPencil: Replace gradient tooltip

Industry Compatible Keymap: initial keymap

This is the initial implementation.

It's fully functional for object and edit mode,
but requires more work in Sculpt and Paint modes.

See T54963

Fix T62449: Subsurf+hidden faces

When using subsurf (and other modifiers) the edit flags are not
propagated correctly. Currently we assume to read the edit flags
from the original object which is kind off hinding the real issue.

Modifiers use `mesh_new_nomain_from_template_ex` to create a copy
from an existing mesh. this method is only used by modifiers. So
by placing this we will make sure that editmesh is propagated.
