[roll third_party/pigweed] pw_span: Introduce pw::span

- pw::span is identical to Pigweed's polyfilled std::span, but in a
  different namespace. Implicit converions between std::span and
  pw::span are supported inherently.

  pw::span and std::span are maintained as separate classes, with shared
  code in a .inc file. This is done instead of aliasing since C++17 does
  not support class template argument decuction with aliases. Also, it
  is simpler to have separate implementations to avoid circular
  dependencies while migrating code to pw::span.
- Add DEFINES to the pw_add_test() CMake function to support defining
  preprocessor macros for the pw_span test.
- Move '.inc' and '.inl' extensions from CPP_HEADER_EXTS to
  CPP_SOURCE_EXTS, since these should be treated like sources not
  headers (no include guards).
