Make ElementInnerTextCollector::ProcessNode() to check LayoutTabelCell

This patch changes  |ElementInnerTextCollector::ProcessNode()| to check object
type before casting to |LayoutTableCell|.

The issue is caused by |LayoutSVGRect|'s computed style of "display" property
is "table-cell".

This patch is follow-up of the patch[1] to fix the bug found by Cluster Fuzz.
