Add --copy-file-range option to pg_upgrade.
The copy_file_range() system call is available on at least Linux and
FreeBSD, and asks the kernel to use efficient ways to copy ranges of a
file. Options available to the kernel include sharing block ranges
(similar to --clone mode), and pushing down block copies to the storage
layer.
For automated testing, see PG_TEST_PG_UPGRADE_MODE. (Perhaps in a later
commit we could consider setting this mode for one of the CI targets.)
