Build with CUDA 12

[pentschev]

Checklist

• Used a personal fork of the feedstock to propose changes
• Bumped the build number (if the version is unchanged)
• Reset the build number to 0 (if the version changed)
• Re-rendered with the latest conda-smithy (Use the phrase @conda-forge-admin, please rerender in a comment in this PR for automated rerendering)
• Ensured the license file is being packaged.

Update UCX to build CUDA 12 from new packaging format and CUDA 10/11 with the legacy cudatoolkit package. Building with qemu segfaults, so switching back to Travis was necessary but that caused ppc64le builds to timeout and were thus disabled, at least until cross-compiling is stable (see #88).

Fixes #82
Closes #86
Closes #89
