Implement X-draw-order switch in TileMapLayer

[groud]

So, I marked it as a bug since setting on Y-sort does end invert the X-drawing order, and I think it should not. So, this makes the default behavior consistent with when Y-sort is disabled.

However, for users who would like the keep the old behavior (which is a valid use case too), I added an x_draw_order_reversed switch.

I think it's a pretty safe change, and it would be very nice to have this bugfix/enhancement in 4.3.

Closes #71257
Closes godotengine/godot-proposals#9882

Was just looking into this too. 😄

Missing docs.

Also while at it:

• there's missing guard in TileMapLayer::set_use_kinematic_bodies,
• in TileMapLayer::set_rendering_quadrant_size dirty flag should be set after the error and assignment.

I've just pushed a new version, I believe everything should be fixed now.

The code LGTM, haven't tested though. 🙃

+Still you could address:

Done!

Rechecked the changes, noticed only another little typo in the docs. Besides looks mergeable to me. 👍

Also briefly tested this, AFAICT it works as intended.

Thanks, should be good now!
