Implement base version of GrantPermissions dialog

With the Emerald release, we need to support the new
permission APIs.  This changelist adds a dialog
for the Activity.requestPermissions() API so that
users can request permissions.

This check in is a functional version, but not polished.
will need to be a follow up CL to add the correct
animations and update the UI to the appropriate redlines.

The implementation for the confirmation dialog is modeled
after the one in the clockwork libs/Views folder.  There
are some tweaks to match the designed behavior of the
permission dialog.  When there's more time in the future,
we should try to condense this to one implementation.

This is a resubmit without the wearable-support lib.
I will figure out how to get that referenced in the next
UI pass.
