pw_digital_io_linux: Refactor test

This separates the mocked file descriptor (VFS) code from the digital IO
test, and provides improved flexibility and clarity of implementing new
files.

This also adds comments to the tests.

Pigweed

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.

For more information please see our website: https://pigweed.dev/.
