fs/buffer: add folio_create_empty_buffers helper
Folio version of create_empty_buffers(). This is required to convert
create_page_buffers() to folio_create_buffers() later in the series.
It removes several calls to compound_head() as it works directly on folio
compared to create_empty_buffers(). Hence, create_empty_buffers() has
been modified to call folio_create_empty_buffers().
