VmLauncherApp: Handle OPEN_URL actions in a handler thread
* When FerrochromeApp is started, enqueue any OPEN_URL Intent to the
thread.
* In the thread, wait and retry until VmAgent connects (indicates VM
boot ready).
* As soon as VmAgent connects, send the OPEN_URL request to VM.
* After the user is switched to the VM activity and unlock the VM
screen, the URL should be open in the VM browser.
Note: Only works consistently if using a non-guest account. If using a
guest account, or switching account, the VM side OPEN_URL request
handling might fail. This still needs investigating.
Bug: 348303697
Test: 0. Ferrochrome OS must already have an user account set up
1. Close the FerrochromeApp
2. Open browser and share a hyperlink to FerrochromeApp
3. FerrochromeApp should launch
4. Unlock Ferrochrome (enter the password / pin of the existing
account)
5. The shared link should be opened by the Ferrochrome browser
