Provide min/max/sum info from zone maps if possible

[myrrc]

For Zoned layout reader, provide info for min/max/sum functions
directly from zone maps if zone maps are included fully.
Decode data for chunks if some zone maps arent't included fully

(Stack for zone maps aggregation short-circuit)

What is the intended semantics of this change/expression. Would you expect this to work over both a layout-reader plan and an array?

Footnotes

1. 55 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on develop (f3d6795) during the generation of this report, so ab4ab65 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩

Things need to be checked via talking with @robert3005 and @joseph-isaacs

1. Are zone maps storing exact values? For aggregate vtable, there is "satisfy" which can be used to check this.
2. String stats are truncated. How does this work vs. non-zone map aggregation?
3. How will stat function semantics change from "upper bound" to "exact" reflect its users?
