internal: reorder ParsedNodeKind for range checks (#907)

## Summary

Reorder `ParsedNodeKind` for range checks, and added named sets to
support querying parsed node kinds.

## Details

Reorder `ParsedNodeKind` in order to support ranges over similar kinds.
This is considered experimental as the motivation for the reodering came
from usage in `suggest` (a consumer). The ordering should be determined
by the `parser` (the producer). Creating these seemingly convenient
consumer/read side ranges end up quietly coupling the producer and
consumer(s). Which results in refactorings to a small collection of
parser modules spilling out to changes in various consumer locations. In
this case these might coincide with the parser's needs, as well.

Additionally, added `pnkDeclarativeDefs` and `pnkRoutineDefs` similar to
`PNode`'s kind, `TNodeKind`.
