resolve: bump *_SEARCH_DOMAIN_MAX to 1024

As prompted by #38393, search domains may be large when a complicated
network setting is used, especially when VPN is used. Let's bump the
limit to 1024.

Note, this does not bump the maximum number of DNS servers, as setting
thousands of DNS servers is spurious and mostly meaningless. Let's keep
the maximum for a while until someone requests to also bump them.

Continuation of b950ee06e647d753db2047c1bb5345c94391be3e.

Closes #38393.
