pw_{span,checksum}: Fix span_impl.h visibility; remove improper includes

- The pw_span/internal/span_impl.h header was not considered private by
  GN, despite being in the sources list. Simplify the pw_span
  pw_source_set to fix this.
- Remove accidentally direct includes of the
  pw_span/internal/span_impl.h header.
- Remove unused _PW_SPAN_POLYFILL_ENABLED macro.

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/.
