**Title:** [v2] Implement LazyInitEmitter for deferred plugin-loading

## Description

*Description of changes:*

* Implemented `LazyInitEmitter`: an alternative event emitter that lazily loads plugins when events that they depend on are emitted. When `building-command-table.main` is emitted, if the plugin only adds/removes to the command table, we wrap the command in a `LazyCommand` wrapper to defer loading the plugin module until the command is invoked or the help docs are generated.
* Implemented unit tests for the new `LazyInitEmitter`.

*Description of tests:*

* Successfully ran pre-production build workflow (see Build Internal GH Action).
