Themes: Allow remote pattern registration in theme.json when core patterns are disabled.

In 6.0 there is now a functionality that allows to register selected remote patterns (from the Pattern Directory) via `theme.json`. However, it requires to fully enable all core and remote patterns. This can be a blocker for user adoption.

Many theme authors want to have all core and remote patterns disabled by default using `remove_theme_support( 'core-block-patterns' )`. This changeset ensures they are serving only patterns relevant to their theme.

It removes theme support check from the function that registers remote patterns specified in `theme.json`. This allows theme authors to disable core patterns but then selectively register the ones they want from the Pattern Directory. If a theme author intentionally specifies patterns in `theme.json`, they probably intend for them to be present in the pattern inserter and the check is not required.

This change will make the Pattern Directory more appealing/usable from a theme author's perspective.
