file_fdw: Support multi-line HEADER option.

Commit bc2f348 introduced multi-line HEADER support for COPY. This commit
extends this capability to file_fdw, allowing multiple header lines to be
skipped.

Because CREATE/ALTER FOREIGN TABLE requires option values to be single-quoted,
this commit also updates defGetCopyHeaderOption() to accept integer values
specified as strings for HEADER option.
