kconfig: add workflow dependencies for NFSD and iSCSI services

Add workflow dependencies to KDEVOPS_SETUP_NFSD and KDEVOPS_ENABLE_ISCSI
to restrict their availability to compatible workflows. Both services are
supported in fstests, pynfs, nfstest, and gitr workflows based on host
template analysis.

This ensures service configuration options are only available when the
selected workflow can actually use them, preventing unused configurations
and missing host groups.
