Fix macOS ARM64 compile errors: update stale cef_types_mac.h and cef_mac.h

The bundled headers were missing CEF 146 macOS additions:
- cef_types_mac.h: add includes for cef_types_color.h, cef_types_osr.h,
  cef_types_runtime.h; add size field to _cef_window_info_t; add
  runtime_style field; add cef_accelerated_paint_info_t; use typedefs
  for handle types instead of macros
- cef_mac.h: init size field in CefWindowInfoTraits, copy runtime_style
  in set(), set runtime_style=ALLOY in SetAsWindowless(), modernize
  CefWindowInfo using base_type alias pattern
