feat(eth): Add support for LAN867X ETH PHY

[me-no-dev]

This pull request adds support for the LAN867x Ethernet PHY to the ESP32 platform. The changes include updating dependencies, conditionally enabling code for the new PHY, and integrating it into the Ethernet library's initialization and configuration logic.

LAN867x PHY Support Integration:

• Added espressif/lan867x as a dependency in idf_component.yml, limited to ESP32 and ESP32P4 targets.
• Defined ETH_PHY_LAN867X_SUPPORTED macro in ETH.h when esp_eth_phy_lan867x.h is available, enabling conditional compilation for LAN867x support.
• Added ETH_PHY_LAN867X to the eth_phy_type_t enum, making it selectable as a PHY type.
• Included esp_eth_phy_lan867x.h and added case handling for ETH_PHY_LAN867X in the Ethernet initialization logic, allowing the library to instantiate and use the LAN867x PHY. [1] [2]

Closes: espressif/esp32-arduino-lib-builder#319
