jfons 55e7832d7b Improvements to SpotLight3D and OmniLight3D's shadows
OmniLight3D:
* Fixed lack of precision in cube map mode by scaling the projection's
  znear.
* Fixed aliasing issues by making the paraboloids use two square regions instead of two half
  squares.
* Fixed shadowmap atlas bleeding by adding padding.
* Fixed sihadow blur's inconsistent radius and unclamped sampling.

SpotLight3D:
* Fixed lack of precision by scaling the projection's znear.
* Fixed normal biasing.

Both:
* Tweaked biasing to make sure it works out of the box in most situations.

reduz cfac8972e1 More optimizations on the mobile renderer.
* Specialization constants used to disable anything not needed to draw
* Added softshadow and projector support on mobile.

This new approach ensures mobile shaders are smaller and more efficient, but relies on more pipeline versions compiled on demand.
As a result, random stalls can ocur like in Godot 3.x. These will be solved by using background compilation and fallbacks eventually (but needs to be tested first).

Clamp negative colors regardless of the tonemapper to avoid artifacts
Color artifacts could be visible when using negative lights with the
Filmic and ACES tonemapping operators, as these did not clamp negative
colors.

reduz 55d357b1eb Fix directional shadow bias
* Simplified code a lot, bias based on normalized cascade size.
* Lets scale cascades, max distance, etc. without creating acne.
* Fixed normal biasing in directional shadows.

I removed normal biasing in both omni and spot shadows, since the technique can't be easily implemented there.
Will need to be replaced by something else.

* Shadow quality settings now specialization constant.
* Decal and light projector filters can be set.
* Changing those settings forces re-creation of the pipelines.

jfons 6995b0429c Assorted fixes to UV unwrapping and GPU lightmapper
Various fixes to UV2 unwrapping and the GPU lightmapper. Listed here for
context in case of git blame/bisect:

* Fix UV2 unwrapping on import, also cleaned up the unwrap cache code.
* Fix saving of RGBA images in EXR format.
* Fixes to the GPU lightmapper:
	- Added padding between atlas elements, avoids bleeding.
	- Remove old SDF generation code.
	- Fix baked attenuation for Omni/Spot lights.
	- Fix baking of material properties onto UV2 (wireframe was
	  wrongly used before).
	- Disable statically baked lights for objects that have a
	  lightmap texture to avoid applying the same light twice.
	- Fix lightmap pairing in RendererSceneCull.
	- Fix UV2 array generated from `RenderingServer::mesh_surface_get_arrays()`.
	- Port autoexposure fix for OIDN from 3.x.
	- Save debug textures as EXR when using floating point format.

jfons 99e1ce0690 Invert spotlight angle attenuation
Inverted the spotlight angle attenuation so a higher value results in
a dimmer light, this makes it more consistent with the distance
attenuation.

Also changed the way spotlighs are computed in SDFGI
and GIPorbes and GPU lightmapper, now it matches the falloff used in the scene rendering
code.
