Add flags to input_verifier

These flags are currently not known by the verifier. As a result, this
causes a panic when such events are trying to get converted to the rust
object.

Add the missing flags in this CL.

Bug: 271455682
Test: manually enable event verification
Test: TEST=inputflinger_tests; m $TEST && $ANDROID_HOST_OUT/nativetest64/$TEST/$TEST
