Options: Add 'label' argument to register_setting.

The 'label' will displayed to users when editing core or custom settings via block editors. It avoids hardcoding Settings labels and improves extensibility.

Backports https://github.com/WordPress/gutenberg/pull/59243.

Props mamaduka, timothyblynjacobs, ellatrix.

Fixes #61023.
