FPII-2766: Don't allow file attachment from /data through GET_CONTENT.

A custom picker can be used to attach files to Compose activity. With
this change, we are disallowing files belonging to file:///data/... to
be attached from custom pickers, in order not to expose internal
application data.

If the Intent Uri is a "file" and the file is in
`Environment.getDataDirectory()`, then throw a
AttachmentFailureException
which is caught immediately and shows a toast to the user.
