Summary

Replace the legacy ESP-IDF I²C driver (driver/i2c.h) with the new driver/i2c_master.h API for all ESP32-series SoCs.
This change:
Removes dependency on the deprecated peripheral driver that is no longer present in ESP-IDF ≥ 6.0.
Keeps the existing machine.I2C API unchanged, so user scripts do not require modification.

Testing

At present, it runs normally on ESP32P4, and others need help to test.
