inputflinger: Add touchpad stack fuzzer
Heavily inspired by MultiTouchInputFuzzer, this one works similarly but
has additional code to fuzz touchpad setting values and device-specific
configuration. The evdev axis info is also fuzzed, since unspecified
resolution values have caused bugs in the Gestures library before.
(Other fuzzers only fuzz the status_t return value from
getAbsoluteAxisInfo, not the axis info struct itself.)
Bug: 264582512
Test: build with SANITIZE_TARGET=hwaddress, run for a while on a device
