Re-organize engine artifacts (flutter#128)

* Re-organize engine artifacts

The artifacts will be:
- tizen-common.zip
- tizen-x86-debug.zip
- tizen-arm-debug.zip
- tizen-arm-profile.zip
- tizen-arm-release.zip
- tizen-arm64-debug.zip
- tizen-arm64-profile.zip
- tizen-arm64.release.zip

The `gen-snapshot(.exe)` is not included in the generated artifacts.
It will be downloaded from the android's artifacts repository by flutter-tizen.
