support wrist orientation in recovery/fastbootd 

Add support for wrist orientation in recovery. Feature controlled by
the property "config.enable_wristorientation".

Read 'ro.boot.wrist_orientation' property to determine if screen
orientation should be flipped and swipes inverted.

Bug: 257123026
Bug: 309982093

Test: build boot/recovery
Test: recovery/fastbootd uses same orientation as android
