Add support for Clang 18 and 19 as CUDA compiler

[SimeonEhrig]

While working on the support of Clang 18 and 19 we found some bugs that prevent the use of Clang 18 and 19 as CUDA compiler. We have decided to disable the support as CUDA compiler in order not to delay the release of version 1.2 too much.

We will check the bug after release and fix it in the next version.
