One Copyright Update to rule them all 
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.

It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).

We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).

Also fixed "cf." Frenchism - it's meant as "refer to / see".

Add maximum roughness cutoff to SSR to improve performance 
In a test scene with mixed rough and non-rough materials, this saves
upwards of 0.15 ms of GPU time with very little visual artifacting
(GTX 1080, 2560×1440).

b2b89d7294 Properly remap roughness when reading from radiance map

381d457a2a Ensure vulkan subgroups are disabled for MoltenVK 
We found they don't work on intel macbooks properly at all.

Possible future solutions:
- update to moltenvk.
- update to spirv may resolve it.

385ee5c70b Implement Physical Light Units as an optional setting. 
This allows light sources to be specified in physical light units in addition to the regular energy multiplier. In order to avoid loss of precision at high values, brightness values are premultiplied by an exposure normalization value.

In support of Physical Light Units this PR also renames CameraEffects to CameraAttributes.

Fade screen-space reflection towards inner margin 
- Fade reflection towards inner margin and clip it at screen edges
  instead of external margin.
- Round edges of the fade margin if both are being cut off to prevent
  sharp corners.
