Adsk contrib - Add support for minimum and recommended versions for dependencies

[cedrik-fuoco-adsk]

Adding support for minimum, maximum and recommended versions for OCIO dependencies.

• Added two new macros to handle the logic: ocio_handle_dependency and ocio_install_dependency.
• The download and install part of each OCIO dependency are now split into two files.
  • Under share/cmake/modules/FindXYZ.cmake and share/cmake/modules/install/InstallXYZ.cmake
• Added an option OCIO_VERBOSE to print more information when CMake is calling the Find modules.
• Refactored what gets printed when we build as well as some colours when modules are found.
• FindOpenImageIO.cmake was removed in favour of their CMake configuration file (as recommended by OIIO). The FindOpenImageIO.cmake that we had was coming from OIIO originally, but it is not supported anymore.
• FindOpenEXR.cmake was removed in favour of their CMake configuration files. Our FindOpenEXR.cmake was basically just doing a search for their CMake's configuration files, but we don't need a whole Find module to do that.

Here's a snippet of a build log:

I am working on the failure in the Linux CI. The issue comes up when OpenImageIO is found via OpenImageIOConfig.cmake. I've identified the issue and I'm working on a solution. The issue is present in the main branch as well.

Sorry, I messed up my branch while trying to rebase. I might have to do a redo.

Closing in favour of https://github.com/AcademySoftwareFoundation/OpenColorIO/pull/1777 (redo)
