Make WindowFrames more specific

[kgyrtkirk]

this patch changes the WindowFrame internals / representation a bit; introduces a dedicated frametype for rows, groups, unbounded - so that later if we decide to add better ranges support it will less likely need a bigger refactor

it also changes how its represented in the native query:

-      frame: { peerType: "ROWS", lowUnbounded: true, lowOffset: 0, uppUnbounded: true, uppOffset: 0 }
+      frame: { type: unbounded }

-       frame: { peerType: "ROWS", lowUnbounded: false, lowOffset: 0, uppUnbounded: false, uppOffset: 2 }
+      frame: { type: rows, lowerOffset: 0, upperOffset: 2 }

-      frame: { peerType: "RANGE", lowUnbounded: true, lowOffset: 0, uppUnbounded: false, uppOffset: 0, orderBy: [{ column: l1, direction: ASC }] }
+      frame: { type: group, upperOffset: 0, orderBy: [{ column: l1, direction: ASC }] }

right now the current patch has some unrelated changes as its built on top of: #15365
