Fix data loss on crash after sorted GiST index build.
If a checkpoint happens during the index build, and the system crashes
after the checkpoint and the index build have finished, the data written
to the index before the checkpoint started could be lost. The checkpoint
won't have fsync'd it, and it won't be replayed at crash recovery either.
Fix by calling smgrimmedsync() after the index build, just like in B-tree
index build.
Backpatch to v14 where the sorted GiST index build was introduced.
