Fonts: Get font-family name from 'fontFamily' field.

Instead of getting the name from the optional `'name'` field, the font-family name now comes from the required `'fontFamily'` field.

This change fixes a back-compat (BC) break in how the font-family name is pulled from the incoming font data in the `WP_Font_Face_Resolver`.

Why?

WP Core does not require the `'name'` field in theme.json. For themes that do not declare it, that set of font variations is ignored, thus causing a BC break from how the stopgap code worked (see [53282]).

However, `WP_Theme_JSON` schema does require the `fontFamily` field in each of the `typography.fontFamilies`.

== Other details:

Includes a parser to extract the first entry when a `fontFamily` field has a comma-separated list of font-families, e.g. `Inter, sans-serif`.
