Code Review
This pull request adds Ethernet support for the ESP32-P4 target. It includes a new sdkconfig for the all-clusters-app example, updates Kconfig to define the GPIO range for ESP32-P4, and bumps the version of the esp_hosted dependency. The changes also improve error handling in the Ethernet initialization path.
The changes are well-structured and seem correct for adding support for the new hardware. I have one minor suggestion in NetworkCommissioningDriver_Ethernet.cpp to maintain consistency with the project's coding style for preprocessor directives.

Pull request overview
Adds an ESP32-P4 Ethernet-focused sdkconfig and small platform tweaks to support running Matter-over-Ethernet on ESP32-P4 boards.
Changes:
- Add
sdkconfig.eth.esp32p4for all-clusters-app to run with Ethernet on ESP32-P4. - Update ESP32 Ethernet driver conditional compilation and ConnectivityManager Ethernet init call.
- Adjust ESP32-P4 GPIO range defaults and pin
esp_hostedcomponent version for ESP32-P4 builds.

Summary
We need to add an example sdkconfig for running Matter-over-Ethernet on ESP32-P4

N/A (not preferable)
Testing
Run all-clusters-app with the newly added sdkconfig on ESP32-P4 Function EV board. The Ethernet interface got IP address and it can be commissioned
