Bind many more properties to scripts

[bojidar-bg]

Notable potentially breaking changes:

• PROPERTY_USAGE_NOEDITOR is now PROPERTY_USAGE_STORAGE | PROPERTY_USAGE_NETWORK, without PROPERTY_USAGE_INTERNAL
• Some properties were renamed, and sometimes even shadowed by new ones
• New getter methods (some virtual) were added

Some notes I did while doing this:

• AnimationPlayer.playback/play became AnimationPlayer.current_animation, with a backward-compatibility fallback. I think I tested this part, but slight bugs are possible.
• Node.filename, Node.name and Node.owner might generate some GDScript errors about shadowing.
• ScrollContainer.h_scroll and ScrollContainer.v_scroll are now scroll_horizontal_enabled and scroll_vertical_enabled.
• CanvasLayer.rotation and Polygon2D.texture_rotation were in degrees, while the new property is in radians. Likely to break a few projects.
• I couldn't really test Control.default_cursor_shape on linux.
• Used OS.window_borderless instead of OS.borderless_window, so we might add a group at a later point.
• Unbound TextEdit.set_max_chars, but added potential bindings for later on, since it wasn't used anywhere. Now I see there is an issue for set_wrap as well, might unbind it as well...
• OS.window_title, Physics{,2D}ShapeQueryParameters.shape and Viewport.attach_to_screen_rect lack getters, so I didn't bind them.
• Added a setter for VehicleBody.linear_velocity, hopefully it works. All the while someone made it extend RigidBody.

While reviewing, please pay attention to the usage of the properties. It should not be PROPERTY_USAGE_NOEDITOR or DEFAULT for properties that are not supposed to be saved to disk.

Let's test in production™ and see what breaks :) This is quite important for 3.0 to have a consistent API.

Hm..

Not sure how those happened, I just ran doctool a few times.

Only the mono build outputs this GodotSharp singleton. For the other issue, not sure.

Hm.. (bis)
