feat(ble): Add function to set pins when using hosted BLE

[lucasssvaz]

Description of Change

This pull request introduces support for configuring SDIO pins for external ESP MCU connections when using ESP-Hosted with NimBLE. The main changes add a new method to the BLEDevice class, allowing users to set the required pins for this setup.

ESP-Hosted NimBLE integration:

• Added the setPins static method to the BLEDevice class in BLEDevice.h, enabling configuration of SDIO pins for communication with an external ESP MCU when ESP-Hosted with NimBLE is enabled.
• Implemented the setPins method in BLEDevice.cpp, which calls hostedSetPins to apply the pin configuration. This method is conditionally compiled when CONFIG_ESP_HOSTED_ENABLE_BT_NIMBLE is set.
