[ECM] Block restricted permission requests (first)

When a permission request occurs for a permission which ECM considers
"restricted" from the app, block it. This means don't actually show the
grant dialog, and instead just show the EnhancedConfirmationDialog
(a.k.a "ECM dialog" or "'Restricted setting' dialog").

If multiple permissions are requested at once, things are a little more
complicated, in that there were different ways we could have chosen to
handle them. We decided to reorder the permission requests as follows:

1. First show the ECM dialog for each of the restricted permissions.
   One dialog should be shown per permission group.
2. Then, move on to normal grant dialog behavior for the remaining ones.

The way that this change implements this is:

1. Intercept GrantPermissionsActivity::onCreate, checking to see if any
   restricted permissions were requested
2. If so, divide the requestedPermissions array into two: restricted and
   unrestricted.
3. For each restricted permission group, show the ECM dialog. This is a
   cross-activity loop, which we handle here using onSaveInstanceState
   to persist our progress, startActivityForResult to wait for each ECM
   dialog instance to end, and finally recreate() which brings us back
   into onCreate.
4. For each remaining unrestricted permission, proceed to normal
   GrantPermissionActivity behavior.

Also, restrict the SMS and Phone permission groups.
