pw_digital_io: Fix provides_*() visibility
Hides provides_{input,output,interrupt}() methods in DigitalIoOptional
subclasses, as they are redundant with the typesystem and should not
be used except via DigitalIoOptional. Exposing these was an oversight
in the initial commit.

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.
