Support aliases in paths

See aliases.

While this may not be a very necessary feature for Polylith since :paths and :extra-paths aren't likely to be anything unusual, this is something supported by core tools.deps.alpha code, and Polylith should not prevent it from being used/working.

Right now, if you try to use aliases in paths -- per Clojure CLI documentation -- Polylith throws an exception:

#error {
 :cause {:paths [["should be a string"]]}
 :via
 [{:type java.lang.Exception
   :message {:paths [["should be a string"]]}
   :at [polylith.clj.core.workspace_clj.config_from_disk$read_config_file invokeStatic config_from_disk.clj 24]}]
 :trace
 [[polylith.clj.core.workspace_clj.config_from_disk$read_config_file invokeStatic config_from_disk.clj 24]

  [polylith.clj.core.workspace_clj.components_from_disk$read_components$fn__30240 invoke components_from_disk.clj 34]

Both calc-basis and make-classpath-map do the unrolling of aliases in paths automatically.

I didn't manage to solve the problem with calc-basis so I simple substituted the paths myself (it's not much code). Please have a look @seancorfield.

I'm not sure what are all the possible combinations in tools.deps.alpha but that PR looks like it covers the basics so it'll be good enough for now. I didn't realize you weren't using t.d.a for handling everything in the deps.edn file.
