Add support for WiFi to ESP32-P4 (#10463)

* feat(p4): Add support for WiFi to ESP32-P4

Implements support for external MCU connected through SDIO

* fix(p4): Init SDIO host properly on Network boot

esp-hosted has one function marked as "constructor" that did not run in the boot phase of the chip. This calls the function when network is started
