Add a 'boolean concurrent' option, and make it work for both cases.
Also rename it to index_create_copy.

This allows it to be reused for other purposes -- specifically, for
REPACK CONCURRENTLY.

With the CONCURRENTLY option, REPACK cannot simply swap the heap file and
rebuild its indexes. Instead, it needs to build a separate set of indexes
(including system catalog entries) *before* the actual swap, to reduce the
time AccessExclusiveLock needs to be held for.  This approach is
different from what CREATE INDEX CONCURRENTLY does.

Per a suggestion from Mihail Nikalayeu.
