Use correct cancel value for gpio_matrix_out on esp32c3

The documentation for gpio_matrix_out on esp32c3 is incorrect
(espressif/esp-idf#11737), and 0x80
needs to be used instead of 0x100.  Add an #ifdef for all of
the supported platforms and use the value listed in the TRM
for each.  The TRM for esp32h2 lists the GPIO Matrix documentation
as "to be added later", so assume the previously used 0x100 value
is correct for that platform.

Fixes FastLED#1498
