  [Dexter] Add support for nested state nodes (#201395)

This patch adds support for nested state nodes, !where and a new !and
node. Nested state nodes are evaluated only at a frame relative to the
frame that their parent matched to:

- `!where` can only match the frame immediately called from/leafwards
from their parent frame.
- `!and` can only match the same frame as their parent frame.
