Twenty Nineteen: Make h1 consistent for entry title.

The h1 for entry-title was not the same between the editor and front end. This fixes that in the by setting wp-block-post-title font sizes together with h2 and combines post-section-dash mixin for both h1 and h2.

Props sabernhardt, nkeller15, shailu25.
Fixes #58440.
