[grid] Fix alignment of baseline sharing groups.

Previously we'd make baseline sharing groups both start aligned. This was incorrect (however correct via. the spec if you read it a certain way). Instead the "major" group should be start aligned, and the "minor" group should be end aligned. See: w3c/csswg-drafts#7645 Change-Id: Iaa04f89e84116acfb9242a1c9cad0e9219f210f1
