[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).
