68678: opt: don't use outer columns as implicit grouping columns r=DrewKimball a=DrewKimball

Previously, the optbuilder logic would add any outer column that is
referenced in a grouping context to the set of grouping columns. This
is correct in some cases, because outer columns are effectively constant,
and can just be removed by norm rules. However, it is incorrect in the
case when there are no grouping columns, e.g. a `ScalarGroupBy`. In that
case, the `ScalarGroupBy` would inadvertently be converted into a `GroupBy`.
This patch modifies the optbuilder to simply ignore outer columns in a
grouping context.

Fixes #68290

68997: stats: use table descriptors instead of IDs r=postamar a=postamar

Previously, the sql stats package inferred various properties about
a table from its ID, like if it is a system or a virtual table.
However the table descriptor is usually readily or easily available,
providing much richer information about a table than its ID.
In particular, this allows us to stop collecting stats for views.

Release note (sql change): table statistics are no longer collected
for views.

69024: colexec: fix bytes corruption for disk-spilled window functions r=DrewKimball a=DrewKimball

This patch fixes the `Truncate` method for bytes columns so that it
updates the offsets to be non-decreasing up to the new `maxSetLength`.
This is necessary in the case when the new `maxSetLength` is greater
than the old one.

This can happen when a window function has a bytes output column and
the `SpillingQueue` that buffers input batches spills to disk. If a
batch has trailing nulls up to the last processed index, and it is
immediately enqueued to disk, `SpillingQueue` does not call `SetLength`
on the batch, so the offsets still need to be updated (in this case by
`Truncate`).
