Implementing app command to query EULA acceptance state for Chrome.

There are 2 parts to this change:
1. Implement setup.exe switch --query-eula-acceptance, and return the result via exit code.
  - Main use case is system-level, which requires the "--system-level" switch.
  - Return code: 0 if "not accepted", 1 if "accepted", and -1 if failed.

2. Add the app command query-eula-acceptance to Chrome binary during installation to execute:
  setup.exe --query-eula-acceptance [--system-level]
