Use SDK macros for matrix detach constants (espressif#8345)

The constants that need to be passed to gpio_matrix_in and gpio_matrix_out
to detach an input or output pin from a peripheral vary by platform.  Use
SIG_GPIO_OUT_IDX to detach an output, and GPIO_MATRIX_CONST_ONE_INPUT
and GPIO_MATRIX_CONST_ZERO_INPUT to detach an input.  ESP32 before IDF 4.0
didn't define GPIO_MATRIX_CONST_*_INPUT, so add compatibility #defines
for GPIO_FUNC_IN_LOW/HIGH.  GPIO_FUNC_IN_LOW/HIGH exist in IDF 4.0+, but
can't be used because they have the wrong values for ESP32-C3 at least
in IDF 4.4.3 (espressif/esp-idf#11737).
