Add support manager to display an error screen or litho form

Summary:
This diff shows the error screen when one of the following condition is met:

- Selected device is not android
- No clients are active for selected device
-  At least there is one client which supports inspector plugin.

For this I have added a SupportRequestManager class which loads the error screen or the litho form based on the above condition.

The UI is super basic. Will improve the design based on your feedback in the coming diffs.
