Update Perfetto and fix tests (#378)

Fix for "SWDEV-479652" - Perfetto-based tests are failing.

Updated version of perfetto submodule to v46.0.
Modified Omnitrace code that uses Perfetto, so it can compile.
Modified the testing code, so it can run the version of trace_processor_shell provided (v46.0).
