Buildfix: Harmony loader is conditionally built via asmdef settings - Originally there was a mix of code macro checks and asmdef constraints - now it's just asmdef constraints and no code defines - Enabled it for all platforms except editor, instead of just 3 explicit ones(Unity's TestFramework currently builds Win32 players instead of Win64). Tests: with PerfFwk enabled and editor in different(Client, Server, both) modes, ran Pool perf tests in Player/standalone mode. Everything built and succeeded.
