Celeste Pan ac63671e4f Bug 2053322 [wpt PR 61132] - [Masonry] Fix content alignment's start and end behavior, a=testonly
Automatic update from web-platform-tests
[Masonry] Fix content alignment's `start` and `end` behavior

Implemented the fix to keep the the definition of keywords `start` and
`end` for content alignment to stay consistent despite `fill-reverse`
and `track-reverse`. The behavior is still up for debate in s CSSWG
issue [1]. In columns, `start` should indicate the top of the container
always, and in row layouts, `start` should indicate the left of the
container always.

Tests were also added for alignment to ensure that `flex-start` and
`flex-end` behave the same as `start` and `end`.
