Editor: Fix writingMode support in dynamic blocks.

Adds missing handling for the `typography.writingMode` property to the style engine, so that dynamic blocks correctly render text orientation styles on the site frontend.

Props wildworks, aaronrobertshaw, poena, get_dave, ndiego.
Fixes #62189.
See #59306.
