Audit CMake for manually handling properties that should be handled by targets or rapids-cmake functions

[vyasr]

#527 and associated work has demonstrated that kvikio's CMake is in need of some clean up. As a starting point, I would like to see

• Use CMake's built-in cufile support if possible, and if necessary add a wrapper in rapids-cmake. Remove the custom find module from kvikio along with its export.
• Use of rapids_cuda_set_runtime to handle linking to cuda targets.
• Removal of direct setting of include directories (and perhaps other properties) that ought to be handled by target linking alone.
• Usage of the ConfigureCUDA module, without which we're not actually setting the compiler flags that we might think.
• Custom CMake settings like this (this one may actually make sense to upstream to rapids-cmake's cpm gtest module in some fashion since I imagine that almost all RAPIDS libraries would be happy with always dumping output on test failures).
