FindCUDAToolkit: Re-unify with Internal/CUDAToolkit

A portion of FindCUDAToolkit was previously split in commit dc2eae1f
(FindCUDAToolkit: Factor out discovery code into a separate file, 2020-04-22)
out into Internal/CUDAToolkit to allow re-use of the code in
CMakeDetermineCUDACompiler for Clang support.

This has turned out to be a bad solution due to Clang requiring quite a bit of
special handling and special handling for NVCC leaking out from
Internal/CUDAToolkit into the Clang code using it.

Thus it seems better to re-unify this code and duplicate the parts of the code
necessary for Clang where it's required. This will help us get logic correct
for both NVCC and CUDA handling. We can still unify the common parts in the
future once the code has matured.
