layout: Don't let table grid boxes inherit display: inline-table (#35264)

Browse source 
The outer display type of a table element applies to the table wrapper
box. The table grid box needs to be block-level as defined in
https://drafts.csswg.org/css-tables/#table-grid-box

Therefore this sets `display: table` on table grid boxes, and then when
painting collapsed table borders we can use the usual logic to compute
the StackingContextSection.
