Add support for Connaxio's Espoir (#6822)

Description of Change

This PR adds support for Espoir, a mikroBUS PoE+ devboard, by Connaxio inc. However, the ESP32-MINI-1 is a single core CPU, so Connaxio will provide the builds for its devboard until single core CPUs are officially supported. Adding these modifications to the official repository will limit discrepancies between Connaxio's fork and the main repo.

Tests scenarios

Tests include Ethernet, SPI, USB, I2C, UART (1-wire).
