Bug 1705784 [wpt PR 28549] - [GridNG] Apply alignment if possible within for the initial geometry., a=testonly Automatic update from web-platform-tests [GridNG] Apply alignment if possible within for the initial geometry. From: https://drafts.csswg.org/css-grid-1/#algo-overview "If both the grid container and all tracks have definite sizes, also apply align-content to find the final effective size of any gaps spanned by such items; otherwise ignore the effects of track alignment in this estimation." This implements the logic for above by adding a bit to the set if all our our tracks have fixed sizes, then using ComputeSetGeometry. The test for this sentence was incorrect, also fixed.

<!-- Heuristic for estimating row-size for orthogonal items should
also consider Content Alignment, so that grid container width is 40px.
