Bug 1673110 [wpt PR 26269] - [GridNG] Implement alignment within grid-areas., a=testonly 

Automatic update from web-platform-tests
[GridNG] Implement alignment within grid-areas.

This patch implements alignment within a grid-item's grid-area.
When creating the GridItemData we read of the containers, and
grid-item's style, or determine its alignment axis-edge, and if it
should be stretched, saving this information on the GridItemData.

When placing the grid-item it will use this to adjust the offset.

This doesn't implement baseline alignment which requires a secondary
pass to correctly determine the baseline for the column/row.

The other TODO relates to the constraint-space API, and how grid will
need a slightly new concept in order to do block-axis stretching
easily. By default non-replaced grid-items will stretch to the available
space. A new bit on the space can indicate that we should stretch to
the available space (if possible), this is similar to the shrink-to-fit
bit we have today.

This adds a self-start/self-end test as after implementing this now new
tests passed immediately, and I don't believe we had good test
coverage for inflow content with these keywords.
