feat(hosted): Add method to update the hosted slave firmware

[me-no-dev]

This pull request introduces updates to the WiFiGeneric module, focusing on enhancing functionality for ESP-HOSTED configurations and improving code maintainability. The most significant changes include adding a new method for updating slave firmware, modifying the inclusion of headers, and adjusting commented-out code for clarity.

Enhancements to ESP-HOSTED functionality:

• Added a new method WiFiGenericClass::updateSlave in WiFiGeneric.cpp and declared it in WiFiGeneric.h. This method facilitates OTA updates for the slave firmware using the esp_hosted_slave_ota function. [1] [2]

Code organization and cleanup:

• Adjusted the inclusion of headers in WiFiGeneric.cpp by uncommenting #include "esp_hosted.h" and commenting out unused headers and declarations, such as esp_hosted_transport_config.h and related functions.
• Added comments in the wifiHostedInit function to explain potential heap exceptions when retrieving the firmware version of older slave firmware.
• Removed an unused extern "C" block after the #include directives for better code clarity.
