Make simulate_stylus_with_touch debug property non-persistent

persist.debug.* properties persist across reboots, and require root
access or debuggable builds to set. On unrooted user builds, these
properties cannot be set.

Change the simulate_stylus_with_touch development feature to use a
non-persistent debug.* property so that it can be set on unrooted user
builds.

Bug: 309036663
Test: adb shell setprop debug.input.simulate_stylus_with_touch true
