Ensure new InputConsumer resampling behavior does not change
Added the last test from TouchResampling_test.cpp to
InputConsumerResampling_test.cpp. This should guarantee that the
resampling part of InputConsumer refactor remains consistent with the
legacy consumer.
Bug: 297226446
Flag: EXEMPT refactor
Test: atest
