UC now returns 0 as the maxCatalogVersion for newly created tables,
instead of -1.

This PR removes code that handled such cases (mapping -1 to the "true"
version of 0).

While we're at it, also does some minor test cleanup and refactors.

Minor logic change. Updated existing UTs.

No.

## Description

Currently when building a commit range start boundary is optional and
defaults to 0 when not provided. However, there is no good use-case
during which the start version is not provided so this PR makes it
required. The prior behavior can always be implemented by the caller by
providing version=0 start boundary.

## How was this patch tested?

Updates/adds tests.

## Description

This PR allows Kernel to set the `delta.dataSkippingStatsColumns` table
property.

Note that (1) its value is not validated/checked, and (2) its desired
behavior is not yet enforced.

## How was this patch tested?

Fairly trivial to add a new table property. Added a new UT nonetheless.

## Does this PR introduce _any_ user-facing changes?

No.

## Description

In
delta-io@7a8c242
I missed removing prior code that pinned the time-travel version to
maxCatalogVersion. This means we weren't actually reading
_last_checkpoint file for latest queries. Since I only added unit tests
for loadLogSegment this wasn't caught in tests.

## How was this patch tested?

Adds a test.

✅ validated the unit test fails without the fix

## Does this PR introduce _any_ user-facing changes?
