//! Registers plugin-related emissions with the master pass so that the
//! dispatch can create the correct output files.
//!
//! Registers two kinds of items:
//! - The plugin infrastructure emission (`PLUGIN_DEFAULT_EMISSION`) for the
//!   `Trampoline` class and `Interop` forwarding methods.
//! - Interface emissions for `IPlugin` and service interfaces.
