Update CI with vfx2023 Linux jobs.

[xlietz]

Below are a list of the CI Linux builds in this PR and relate Imath PR (will add link in comment).

Questions for both Imath and OpenEXR :

• Do we still need c++14 builds for 2023? Imath had them for 2022, OpenEXR did not.
• Do we need static debug builds for 2023? OpenEXR had them for 2022, Imath did not.
• Do we need clang builds for prior years? Imath had them for 2022, OpenEXR did not.
• Any other builds I should drop or add?
• Should we be using Clang 14.0 or 15.0 for 2023? AFAICT the docker image has both.

• clang 14/15 are meaningful to xcode targets we support.
• all compilers specified in 2023 vfxplatform support c++ 17, so dropping 14 should be fine
• static debug is helpful in general because people do build against them
• i recommend we drop cy2019 in the spirit of current year + 3.
• 2020 clang 7.8 python 3.7.3 C++14 - I am not aware of any platform we support where clang 7 is a requirement, recommend dropping
