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.

This only works if zone maps are precise so we check this both for normal and legacy stats.

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

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?

[myrrc]

Additional issue to check: Struct array with nullability may produce invalid zone maps (containing invalid but defined values)
