FindCUDA: Use find_program if find_host_program is not available

Browse Source 
CMake does not define the `find_host_program` command we've been using
in the cross-compiling code path.  It was provided by a widely used
Android toolchain file.  For compatibility, continue to use
`find_host_program` if available, but otherwise use just `find_program`.

Fixes: #16509
