Simon Sapin 56345cdab0 layout: Fix which axis to consider for baseline propagation of flex items (#44281) ...

* When a flex item line participates in baseline alignment, the relevant
baseline must be parallel to the **main axis** (affected by
`flex-direction`) of the flex container.
* When a flex item propagates a baseline to a parent layout (such as for
`display: inline-flex`) the relevant baseline must be parallel to the
**inline axis** (not affected by `flex-direction`) of the flex
container.
