Remove TWRP app prompt from reboot flow

Add option to install TWRP app as a list menu item on the
advanced page and as a button on the reboot page (except for
watch theme). Now when a user reboots the device, they no longer
will be prompted to install the TWRP app, which interrupts the
flow of rebooting the device.
