This change avoids polyfilling the constinit and constexpr keywords,
which requires implicit polyfilling. Instead, this introduces a macro
that is straightforward to use and portable.
- Remove consteval and constinit language feature polyfills.
- Provide PW_CONSTINIT macro that uses the constinit keyword or compiler
attributes to guarantee constant initialization.
- Update PW_CONSTEVAL so it always marks functions constexpr.

- Update labels so they use consistent naming. Instead of the
copy-and-pasted `chapter` prefix, name labels with a prefix consistent
with what they point to:
- "module-" for module
- "target-" for targets
- "docs-" for general documentation
- Remove the unnecessary highlight and default-domain directives.
Neither is necessary since the Pigweed docs always specify the
language in code snippets and other directives.

- Implement std::endian from <bit> (__cpp_lib_endian).
- Replace pw::ByteOrder with std::endian.
- Update the <span> header to use the same approach as <bit> and define
the appropriate std::span feature macro.

- The module's overrides are added to the GN build to seamlessly
support older C++ standards.
