enable device to customize setup activity via RRO

Device makers can provide an input id to setup activity
package and class name mapping table to LiveTv via RRO.
LiveTv launches the overlay setup activity instead and
fallbacks to the setup activity defined in TIS.

Bug: 264504967
Bug: 258580153
Test: m, boot Falcon, launch LiveTv check below
Test: without valid overlay, Intent creation fallback to existed flow
Test: with valid overlay, Intent can launch overlay setup activity
