Handle multiple passes of scope and defparam elaboration.
...
When generate schems and instance arrays are nested, it takes
multiple iterations of elaborate scope, defparams and evaluate
parameters before everything is worked out. Rework the work item
processing so that the loop elaborates scopes and runs defparams
in phases. The phases are needed so that we can tell when the
remaining defparams are orphaned.

Modules mentioned within generate schemes are not candidates for

Run generate schemes after defparams.
...
We must run generate schemes after running defparams because the
defparams may define the results of the generate schemes. So put
the generate schemes for a module scope into elaborator work items.

Handle indexed defparams.
...
The l-value of a defparam assignment is a hierarchical name that may
include array selects to select scopes from module arrays. Therefore
it makes no sense to store parsed defparams in a map. Instead, they
should go into an ordered list. This also maked more sense because later
defparams *may* have the same name as a previous defparam, and will
override the previous defparam. So replace the map of parsed defparams
with a list of parsed defparams.
Also, as soon as the defparam expression is elaborated, the list entry
is no longer needed, so delete it. Save memory.
