esp32/esp32_common.cmake: Use the tinyusb source files from ESP-IDF.

This commit removes the explicit dependency on the vendored tinyusb
version for the ESP32S2 and ESP32S3 boards.

Tinyusb is still available to MicroPython through a dependency on the
`espressif/esp_tinyusb` ESP-IDF component, which in turn depends on
the `espressif/tinyusb` component itself.
