Thomas Munro f94e9141a0 Add file_extend_method=posix_fallocate,write_zeros. 
Provide a way to disable the use of posix_fallocate() for relation
files.  It was introduced by commit 4d330a61bb.  The new setting
file_extend_method=write_zeros can be used as a workaround for problems
reported from the field:

 * BTRFS compression is disabled by the use of posix_fallocate()
 * XFS could produce spurious ENOSPC errors in some Linux kernel
   versions, though that problem is reported to have been fixed

The default is file_extend_method=posix_fallocate if available, as
before.  The write_zeros option is similar to PostgreSQL < 16, except
that now it's multi-block.
