Update SPIR-V CSV Options (#774)

* Update `opencl_conformance_tests_21_full_spirv.csv` with
`/-offlineCompiler/--compilation-mode` and
`/cache/--compilation-cache-path` in order to match the offline
compilation options in the cts executables. Do not add the
`--compilation-cache-mode` and `--compilation-program` options since
they are user specific and the default values are generic.

* Delete `opencl_conformance_tests_generate_spirv.csv` since there is no
longer a `generate` option for offline compilation in the cts
executables.
