Lioncash da7be67daf ipc_helpers: Remove usage of the global system instance
Resolves numerous deprecation warnings throughout the codebase due to
inclusion of this header. Now building core should be significantly less
noisy (and also relying on less global state).

This also uncovered quite a few modules that were relying on indirect
includes, which have also been fixed.
