  1. Add Linux/ELF support to base headers (gated, MSVC-identical) 

    Port the proven WSL/ELF spike edits into the strings/*.h source-of-truth so
cppwinrt.exe regenerates a Linux-buildable winrt/base.h. All edits are gated
behind !_WIN32 / __GNUC__+ELF so MSVC output is byte-identical:

- base_macros.h: platform-shim block (__stdcall, WINRT_IMPL_SELECTANY,
  WINRT_IMPL_64 LP64 macro, six inline GCC-builtin interlocked shims).
- base_activation.h: interlocked_read_32/64 GCC branches; six _WIN64 gates
  widened to (defined(_WIN64) || defined(WINRT_IMPL_64)); SLIST #error guard
  relaxed for GCC/ELF on x86/x64/arm64.
- base_extern.h / base_natvis.h / base_version.h: __declspec(selectany) ->
  WINRT_IMPL_SELECTANY (weak symbol on non-MSVC).
- base_includes.h: guard <intrin.h> behind _WIN32.
