Move handling for debug accelerators to debug_commands.*

This CL also:
- Adds the 'DEBUG' prefix to all debug accelerators actions
- Enables all debug accelerators when --ash-debug-shortcuts is passed.
- Removes special logic to enable certain accelerators only in a debug build.
- Makes Chrome handle debug accelerators before sending the accelerators to the
  renderer. Previously some debug accelerators (but not all) could be disabled
  by apps. This CL removes this functionality.
