Merge pull request #223 from HiIAmMoot/profiling-cpu

Add a profiling build: CPU recordings for Perfetto and a report tool

Conflicts resolved: CI runs main's tests and test_profile.py; the build
scripts take both main's opus and target flags and the PR's
configuration_defines; port_config.c keeps debug.memory_watch before the
profile settings; main.c and network_distributed.c keep voice chat, and
network_votekick_host_tick stays its own statement after the game state's
profile scope, not under its if.
