net: hns3: unify copper port ksettings configuration path

Refactor hns3_set_link_ksettings() and hclge_set_phy_link_ksettings()
to unify the configuration path for copper ports.

Previously, netdevs with a native kernel phy attached bypassed the main
MAC parameter caching logic and returned early via
phy_ethtool_ksettings_set(). This prevented the driver from updating
hdev->hw.mac.req_xxx variables for kernel PHY setups, leaving them
out-of-sync during reset recovery.

Clean this up by routing all copper port configurations through
ops->set_phy_link_ksettings(), and perform driver-level or kernel-level
PHY arbitration inside hclge_set_phy_link_ksettings() via
hnae3_dev_phy_imp_supported(). This ensures that the user's intended link
profiles (req_speed, req_duplex, req_autoneg) are uniformly recorded
across all copper and fiber deployment topologies, laying the groundwork
for stable reset recovery.

For copper ports where neither IMP firmware nor a kernel PHY is available
(e.g. PHY_INEXISTENT), hclge_set_phy_link_ksettings() returns -ENODEV.
In hns3_set_link_ksettings(), this is caught so the configuration falls
through to the existing MAC-level path (check_ksettings_param ->
cfg_mac_speed_dup_h), preserving compatibility with PHY-less copper
deployments.
