[Perf] private_footprint_size memory usage is constantly increasing for pixel4 bot #38334

memory:chrome:all_processes:reported_by_os:private_footprint_size is constantly increasing overtime.

It looks like each new revision consumes more memory than previous. In fact, relaunching the tests on the old revisions also give more numbers than in the original measurements. We definitely remove remove the old package before testing a new one.

On the other hand, memory:chrome:all_processes:reported_by_chrome:allocated_objects_size is fine and matches to the changes in the real memory consumption of the C++ code.
