ignore delmark when add minmax for pk column

[lidezhu]

What problem does this PR solve?

Issue Number: close #4747

Problem Summary:
If rows in a stable pack is all mark deleted, then it's minmax index for pk column is both 0.
And when dt_enable_skippable_place is enabled and try to place delta index on this segment, it will filter out all pack which is not in the pk range [start_key, +infinite). So the previous stable pack is ignored.
But for the place delta index algorithm, it's expected that all the rows in the pk range [start_key, +infinite) is placed no matter whether it's deleted. So when we try to read this segment using the placed delta index, it reports error like "DeltaMerge return wrong result"

What is changed and how it works?

Ignore delmark when add minmax for pk column.
