Remove static struct members from layout and reflection (#1310)

* * Added MemberFilterStyle - controls action of FilteredMemberList and FilteredMemberRefList
* Splt out template implementations
* Use more standard method names dofr FilteredMemberRefList
* Added reflect-static.slang test
* Added isNotEmpty/isEmpty to filtered lists
* Added ability to index into filtered list (so not require building of array)

* Default MemberFilterStyle to All.

* Remove explicit MemberFilterStyle::All
