CMakeDetermineCompilerABI: pass verbose flag during compilation

Default to the same flag that is used for verbose link information, but
provide another internal platform information variable to use a
compilation-specific variant.  Populate it for CUDA where we use a
different compiler for compilation and linking and therefore need
different flags.
