e1b3d91127 Refactor: replace Cycles sse/avx types by vectorized float4/int4/float8/int8
The distinction existed for legacy reasons, to easily port of Embree
intersection code without affecting the main vector types. However we are now
using SIMD for these types as well, so no good reason to keep the distinction.

Also more consistently pass these vector types by value in inline functions.
Previously it was partially changed for functions used by Metal to avoid having
to add address space qualifiers, simple to do it everywhere.

Also removes function declarations for vector math headers, serves no real
purpose.

230f9ade64 Cycles: make transform inverse match Embree exactly
Helps improve ray-tracing precision. This is a bit complicated as it requires
different implementation depending on the CPU architecture.

023eb2ea7c Cycles: more closely match some math and intersection operations in Embree
This helps with debugging, and gives a slightly closer match between CPU
and CUDA/HIP/Metal renders when it comes to ray tracing precision.

c2a2f3553a Cycles: unify math functions names
This patch unifies the names of math functions for different data types and uses
overloading instead. The goal is to make it possible to swap out all the float3
variables containing RGB data with something else, with as few as possible
changes to the code. It's a requirement for future spectral rendering patches.

9cfc7967dd Cycles: use SPDX license headers
* Replace license text in headers with SPDX identifiers.
* Remove specific license info from outdated readme.txt, instead leave details
  to the source files.
* Add list of SPDX license identifiers used, and corresponding license texts.
* Update copyright dates while we're at it.

fd25e883e2 Cycles: remove prefix from source code file names
Remove prefix of filenames that is the same as the folder name. This used
to help when #includes were using individual files, but now they are always
relative to the cycles root directory and so the prefixes are redundant.

For patches and branches, git merge and rebase should be able to detect the
renames and move over code to the right file.
