Enable streaming of GrantPermissionsActivity

Remove the VDM streaming opt-out via canDisplayOnRemoteDevices=false
from the activity definitions in AndroidManifest.xml.

When GrantPermissionsActivity shows a permission request on a
VirtualDevice the request shows additional information about the device
that the permission will take effect on.

This effectively changes the language from: "Allow <app> to access
<permission>" to "Allow <app> to access <permission> on <device>".

Permission dialogs shown on the default device are unchanged.

Feature is flagged via the virtual_devices flag stream_permissions.
