Handle an instant view table with no rows

ProcessTable computed its column count with table.Cells.Max(...), which throws
InvalidOperationException: Sequence contains no elements when the table has no
rows at all. It reached OnApplyTemplate through InstantContent.UpdateView, so
the whole message failed to render. Reported by crash telemetry on 12.9.1.

There is no grid to build for an empty table, so render just the caption --
which is what the method already falls back to, and callers of ProcessBlock all
handle a null return.

Not built: no UWP/.NET Native build environment here. Verified the file still
parses with Roslyn.
