This is a feature under discussion in RFC 95, implemented behind a symbol.

It allows components to access dynamically scoped variables via:

import { DYNAMIC_VAR_PARAMS } from 'ember-glimmer/utils/process-args';
MyComponent.reopenClass({
  [ DYNAMIC_VAR_PARAMS ]: [ 'outletState' ]
})

I intend to use it next within the LinkComponent as part of a refactor to make link-to cleaner and faster.

This PR depends on glimmerjs/glimmer-vm#332 and #14355.

This cleans up and unifies the handling of curly comopnent arguments. It splits the work into two distinct phases

 - gatherArgs assembles an EvaluatedArgs that combines all variations of positional and named arguments into a single EvaluatedArgs object
 - ComponentArgs.create takes the EvaluatedArgs and produces the curly-component specific attrs & props structures with mutable cells, etc.

I think that we decided not to move forward on this (and emberjs/rfcs#95 ended up sticking to get-outlet-state and set-outlet-state). I'm going to close this (based on that assumption), please reopen if you disagree...
