Use va_name config for all artist fields on VA releases

When importing compilations, albumartist_sort, albumartists_sort,
albumartist_credit, albumartists_credit, and albumartists were
hardcoded to "Various Artists" instead of using the user-configured
va_name setting. This also fixes the same issue in the beatport plugin.

Fixes #6316
