8392ca915b Cycles: Remove glog dependency, redirect logs to CLOG
* Add own simple logging system to replace glog, which is no longer
  maintained by Google.
* When building in Blender, integrate with CLOG and print all messages
  through that system instead.
* --log cycles now replaces --debug-cycles. The latter still works but
  is no longer documented.

dd51c8660b Refactor: Cycles: Add const keyword where possible, using clang-tidy
Check was misc-const-correctness, combined with readability-isolate-declaration
as suggested by the docs.

Temporarily clang-format "QualifierAlignment: Left" was used to get consistency
with the prevailing order of keywords.

945579c203 Fix Cycles build issue with USD 23.02
HdRenderDelegate got a change with the interface, adding gpuSupported. It
currently is just a dummy implementation without checking for anything
GPU-related.

d32d787f5f Clang-Format: Allow empty functions to be single-line
For example

```
OIIOOutputDriver::~OIIOOutputDriver()
{
}
```

becomes

```
OIIOOutputDriver::~OIIOOutputDriver() {}
```

Saves quite some vertical space, which is especially handy for
constructors.

0de0950ad5 Cycles: various Linux build fixes related to Hydra render delegate
* Add missing GLEW and hgiGL libraries for Hydra
* Fix wrong case sensitive include
* Fix link errors by adding external libs to static Hydra lib
* Work around weird Hydra link error with MAX_SAMPLES
* Use Embree by default for Hydra
* Sync external libs code with standalone
* Update version number to match Blender
* Remove unneeded CLEW/GLEW from test executable

None of this should affect Cycles in Blender.

d350976ba0 Cycles: Add Hydra render delegate
This patch adds a Hydra render delegate to Cycles, allowing Cycles to be used for rendering
in applications that provide a Hydra viewport. The implementation was written from scratch
against Cycles X, for integration into the Blender repository to make it possible to continue
developing it in step with the rest of Cycles. For this purpose it follows the style of the rest of
the Cycles code and can be built with a CMake option
(`WITH_CYCLES_HYDRA_RENDER_DELEGATE=1`) similar to the existing standalone version
of Cycles.

Since Hydra render delegates need to be built against the exact USD version and other
dependencies as the target application is using, this is intended to be built separate from
Blender (`WITH_BLENDER=0` CMake option) and with support for library versions different
from what Blender is using. As such the CMake build scripts for Windows had to be modified
slightly, so that the Cycles Hydra render delegate can e.g. be built with MSVC 2017 again
even though Blender requires MSVC 2019 now, and it's possible to specify custom paths to
the USD SDK etc. The codebase supports building against the latest USD release 22.03 and all
the way back to USD 20.08 (with some limitations).
