`tableFrame` is seldom used, and all the functions that need the table frame
have already got it via `GetTableFrame()` helper.

We don't need set `haveRow` to `true` in every iteration in the loop over table
rows. It is sufficient to check `GetFirstRow()`.

* It used to return useless `nsresult`. Change it to return the block-size
instead of modifying the argument to return value.
* Shorten its name to `CalcCellActualBSize` to match `CalcBSize`.

While I'm here, revise GetFirstRow(), GetLastRow(), and GetNextRow(), and add
assertions to them to ensure the correctness of table frame tree structure.

We don't ever remove `NS_TABLE_ROW_HAS_UNPAGINATED_BSIZE` bit, so let's set the
bit directly in `SetUnpaginatedBSize()`.
This patch doesn't change behavior.

This is in order to eventually remove the destruct root.
This is a performance optimization to avoid doing the work of
registration if the table is about to go away anyways. The only thing
this wants to check is whether the first continuation is getting
destroyed. We can do that much more easily, explicitly.

This shouldn't change behavior, but it packs the two arguments to
DestroyFrom into a single thing, and makes nsIFrame::Destroy not so easy
to call without a previous context.
This is a prerequisite to pass aDestroyContext to various things that
right now just mint one, which can cause badness, see bug 1851787 and
related bugs.
It's also a bit nicer to add things there if we need to in the future.

While looking at the backout, I noticed table parts relied on reframing
on abspos-container-ness changes in a subtle way, see the test, which
fails with the first patch of this bug applied without these changes.
Make the NS_FRAME_CAN_HAVE_ABSPOS_CHILDREN mean the same for table parts
as for everything else. Instead, keep the registration status on each
relevant frame class individually.
Depends on D169127

- Remove unnecessary calls to ClearSize() after declaring a fresh ReflowOutput.
- Use ReflowOutput::SetSize() in nsTableFrame::FixupPositionedTableParts().

After this patch, we still need nsFrameList::Enumerator to iterate
nsFrameList::Slice. We might enhance nsFrameList::Iterator to support Slice, but
I'll leave this for another day.

In the description of the mTruncated bit, its purpose is the same as calling
SetInlineLineBreakBeforeAndReset(). We've removed all its usages in previous
patches, so the bit is no longer needed.

See bug 1758757 comment 0 for the rationale.
Note: the old code in nsTableRowGroupFrame::SlideChild() is bogus because it
calls ApplyRelativePositioning() via the nsTableRowGroupFrame's ReflowInput
instance. That is, it applies relative positioning to nsTableRowGroupFrame, but
not to the aKidFrame (nsTableRowFrame).
While I'm here, I expand `SlideChild` in its only caller, and simplify it.
