Eevee: Shadow: Fix, improve cascade shadow map UI.

Eevee: Shadows: Add cubemap filtering and adaptive sample count.

Filter size is constant in world space and not dependant of shadow resolution.
The filter size is limited to the number of precomputed samples.

Eevee: Shadow: Fix Incorrect shadowing after sun lamp far clip plane.

Reject cascade sample if not in shadowmap volume.

Eevee: Shadows: Filtering improvement.

- Replace poisson by concentric samples: Less variance. They are sorted by radius then by angle.
- Separate filtering into 2 blur. First blur is 3x3 box blur. Second is user dependant.
- Group fetches by group of 4.

Eevee: Add Cascaded Shadow Map options.

Lamps: Remove uper limit of the buffer bias parameter.

Eevee: Add Cascaded Shadow Map support with filtering.

This brings some data structure changes.
Shared shadow data are stored in ShadowData (in glsl) (aka EEVEE_Shadow in C).
This structure contains the array indices of the first shadow element of this shadow "object".
It also contains how many shadow to evaluate (to be used for Multiple shadow maps).

The filtering is noisy and needs improvement.

Eevee: Shadow: Add high bitdepth option.

This option is here for reducing the memory usage of shadow maps.

Also lower bitdepth are quicker to process.

Eevee: Expose Shadow filter size.

Eevee: Add Variance Shadow Mapping

This is an alternative to ESM. It does not suffer the same bleeding artifacts.

Eevee: Shadows: Add UI buttons for size and method

Only one method is available right now. VSM and PCF are comming.

Eevee: Refactor Shadow System

- Use only one 2d texture array to store all shadowmaps.
- Allow to change shadow maps resolution.
- Do not output radial distance when rendering shadowmaps. This will allow fast rendering of shadowmaps when we will drop the use of geometry shaders.

Resolve T52687: Add node label shows as 'Unknown'

Add type access method, need to extend to other types
for now just get node UI working properly again.

PyAPI: Fix mathutils freeze allowing owned data

Docs: mathutils docstrings

Cleanup: mathutils vector comments

Use doxy markup & correct outdated info.

Correct last commit

Cleanup: Simplify SWIZZLE macro

- Use indices instead of character args.
- Use numbered macros instead of variadic args.

Parsing using rtags used over 11gb of memory. While this should be
resolved upstream (report as #1053), the extra complexity didn't give
any real advantage.

[msvc/make.bat] mention the msvc-2017 option in the make.bat help text.

Cycles: Attempt to work around compilation of sm_20 and sm_21

Disabled forceinline for those architectures, which seems to be compiling
successfully more often.

There might be ~3% slowdown based on quick tests, but better be rendering
something rather than failing to compile kernels again and again.

Those architectures will be doomed for abandon once we'll switch to toolkit 9.
