Previously the cmake code would try to run the LIBDIR specific "findX.cmake" files for both vulkan and shaderc.
However these would pick up system headers and libraries when LIBDIR were not present. This would lead to compilation errors as the system library configurations were not taken into account or queried.
This changes it so that if LIBDIR is not present, the proper pkgconfig files will be used instead.

The `Find*.cmake` modules originally used uppercase commands to match
CMake's own conventions. Since then CMake uses lower-case and even
within our own find modules, using all uppercase wasn't done
consistently. Opt for lowercase everywhere.
Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
Paths to vulkan libraries, paths and related components were
hardcoded in the platform cmake file. This patch separates
this by using adding CMake modules for Vulkan and ShaderC.
This change has only been applied to the macOs configuration as
that is currently our main platform for development. Other platforms
will be added during the development of the Vulkan back-end.
