Revert "Remap accessing action bar shortcut to META+CTRL+TAB"

Revert submission 23374698-update_meta_ctrl_shortcut

Reason for revert: This fix is problematic
1. The logic in ViewRootImpl uses CTRL+TAB in the latest patch. CTS test is probably unrelated to the change in ViewRootImpl.
2. Since this should be fixed in UDC (a cherry pick is in flight), will try to find a fix in the next few days in udc

Fix forward: ag/23407268
