Support macro parameters in filter run prefixes (#6164)

* Support macro params in filter run prefixes and support substitution for variables set by filter run prefixes

* feat: add support macro parameters and variable substitution for all filter run prefixes

* fix: rename options argument to opts for disambiguation

* feat: add support for macro params to cascade filterrun prefix
