Add missing CUDA 12 dependencies and fix dlopen library names

[vyasr]

Description

The dropping of system CTK libraries from our CUDA 12 CI images revealed that we were missing the cuda-nvcc package required to provide nvvm for numba in the Python tests. They also revealed that the list of libraries we searched to dlopen is incomplete; for CUDA 11, the SONAME of the library incorrectly includes an extra .0 version segment, and rmm was designed to search for that, but CUDA 12 correctly has just libcudart.so.12 and that needs to be added to the search path. We were previously getting by on finding libcudart.so, but the linker name is only present in conda environments if cuda-cudart-dev is installed, and that package should not be a runtime requirement for rmm.
