esp32/network_lan: Add PHY_GENERIC device type.

Support the new PHY_GENERIC device type, added in ESP-IDF v5.4.0 [1].

This PHY driver was added to ESP-IDF to support "generic"/oddball PHY
LAN chips like the JL1101, which offer no features beyond the bare
802.3 PHY standard and don't actually need a chip-specific driver (see
discussion at [2]).
