Add inputflinger InputReader fuzzer
This CL aims to add a fuzzer to test inputflinger's InputReader
functionality.
Test: Fuzzers tested on a Pixel 3a, and run for approximately 1M
iterations each to test stability. Executions/sec vary from
~400-900, depending on the fuzzer.
Summary of updates:
Coverage improvements: 36.75% to 82.29%
Design changes:
[1] Provided a mock Implementation for InputReaderInterface and
added support for newer APIs.
[2] Enabled support for few more Events that helped in discovering
new code paths.
[3] Added missing APIs and resolved OOB Access crashes.
[4] Refactored InputReaderFuzzer to resolve build errors.
