esp32/mphalport: Add function/line/file info to check_esp_err exception. 

Currently, check_esp_err() raises an exception without a location in the
source code, eg:

    Traceback (most recent call last):
      File "<stdin>", line 8, in <module>
    OSError: (-258, 'ESP_ERR_INVALID_ARG')

This commit allows additional error reporting (function, line and file) to
be enabled via detailed exceptions.  Change the error reporting config to

    #define MICROPY_ERROR_REPORTING (MICROPY_ERROR_REPORTING_DETAILED)

and then exception messages from IDF errors look like:

    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    OSError: (-258, "0x0102 ESP_ERR_INVALID_ARG in function 'set_duty_u16'
    at line 342 in file './machine_pwm.c'")
