66f826ae85 Benchmark: Add eevee viewport playback tests.
This commit adds the ability to test Eevee viewport playback performance tests.

Tests should be placed in `lib/benchmarks/eevee/*/*.blend`. {rBL62962} added
initial test files. See https://wiki.blender.org/wiki/Tools/Tests/Performance how
to set it up.

To record the playback performance the test start the viewport playback, and adds
a post frame change handler.

This handler will go over the next steps:

* Ensures the viewport is set to rendered mode.
* Wait for shaders to be compiled. Utilizes `bpy.app.is_job_running` function when
  available (v3.3) to wait for shader compilation to finish. When not available will wait
  for one minute.
* Draw several warmup frames
* Record for 10 seconds tracking the number of frames drawn and performance counters.
* When ready print the result to the console. The results will be extracted when the
  benchmark has run.

c434782e3a File headers: SPDX License migration
Use a shorter/simpler license convention, stops the header taking so
much space.

Follow the SPDX license specification: https://spdx.org/licenses

- Python
- Shell Scripts
- CMake, GNUmakefile

While most of the source tree has been included

- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they
  use different header conventions.

doc/license/SPDX-license-identifiers.txt has been added to list SPDX all
used identifiers.

See P2788 for the script that automated these edits.

0803119725 Cycles: merge of cycles-x branch, a major update to the renderer
This includes much improved GPU rendering performance, viewport interactivity,
new shadow catcher, revamped sampling settings, subsurface scattering anisotropy,
new GPU volume sampling, improved PMJ sampling pattern, and more.

Some features have also been removed or changed, breaking backwards compatibility.
Including the removal of the OpenCL backend, for which alternatives are under
development.

Credits:
* Sergey Sharybin
* Brecht Van Lommel
* Patrick Mours (OptiX backend)
* Christophe Hery (subsurface scattering anisotropy)
* William Leeson (PMJ sampling pattern)
* Alaska (various fixes and tweaks)
* Thomas Dinges (various fixes)

For the full commit history, see the cycles-x branch. This squashes together
all the changes since intermediate changes would often fail building or tests.

e43ecca016 Tests: measure time per frame in animation performance benchmark
Instead of a fixed number of frames, so that benchmarking takes about the
same time on any machine.

37a5ff4a84 Tests: support graphing peak memory in Cycles performance tests
The general graphing mechanism will create one graph for each output
variable. So it's not limited to time and memory, but that is what the
Cycles tests now output.

dc3f46d96b Tests: performance testing framework
These are scripts for benchmarking Blender features on real-world .blend
files. They were originally written for benchmarking Cycles performance, and
were made generic so they can be used for more Blender features.

The benchmarks can be run locally by developers. But the plan is to also run
these as part of continuous integration to track performance over time.

Currently there are tests for Cycles rendering and .blend file loading.

Documentation:
https://wiki.blender.org/wiki/Tools/Tests/Performance

Main features:
* User created configurations to quickly run, re-run and analyze a selected
  subset of tests.
* Supports both benchmarking with existing builds, and automatic building of
  specified git commits, tags and branches.
* Generate HTML page with bar and line graphs from test results.
* Controlled using simple command line tool.
* For writing tests, convenient abstraction to run a Python function in Blender
  with arguments and return value.
