comma: support filter, watch, poll (nushell#707)

- Supports `computed`, the definition method refers to `$env.comma_scope.computed`, accepts two parameters, runtime parameters and `$env.comma_scope` - Supports `filter`, similar to `computed`, but only runs when declared, specified through `$env.comm.flt` - Supports `watch`, specified through `$env.comm.wth`. Support polling like 'poll:2sec' --------- Co-authored-by: nash <[email protected]>
