[masonry] Optimize grid items with a span 1
https://bugs.webkit.org/show_bug.cgi?id=276385
rdar://problem/131407028
Reviewed by Sammy Gill.
General Case: grouping auto-placed items by span size -> Nitems + Ntracks x
Nspans
- compute aggregate items (Nitems)
- apply to tracks (Ntracks x Nspans)
This implements the algorithm for single track items. Items that span multiple
tracks
and items that are 'fr' will be handled in a follow up patch.
Runtime on microbenchark was reduced from 1.2 seconds to 38 ms.
Benchmark tested 1000 columns with 'auto' and 10,000 grid items.
Tested on M1 Ultra.
