  Add and use `SDL_FALLTHROUGH` for fallthroughs
  
  Case fallthrough warnings can be suppressed using the __fallthrough__
  compiler attribute. Unfortunately, not all compilers have this
  attribute, or even have __has_attribute to check if they have the
  __fallthrough__ attribute. [[fallthrough]] is also available in C++17
  and the next C2x, but not everyone uses C++17 or C2x.
  
  So define the SDL_FALLTHROUGH macro to deal with those problems - if we
  are using C++17 or C2x, it expands to [[fallthrough]]; else if the
  compiler has __has_attribute and has the __fallthrough__ attribute, then
  it expands to __attribute__((__fallthrough__)); else it expands to an
  empty statement, with a /* fallthrough */ comment (it's a do {} while
  (0) statement, because users of this macro need to use a semicolon,
  because [[fallthrough]] and __attribute__((__fallthrough__)) require a
  semicolon).
  
  Clang before Clang 10 and GCC before GCC 7 have problems with using
  __attribute__ as a sole statement and warn about a "declaration not
  declaring anything", so fall back to using the /* fallthrough */ comment
  if we are using those older compiler versions.
  
  Applications using SDL are also free to use this macro (because it is
  defined in begin_code.h).
  
  All existing /* fallthrough */ comments have been replaced with this
  macro. Some of them were unnecessary because they were the last case in
  a switch; using SDL_FALLTHROUGH in those cases would result in a compile
  error on compilers that support __fallthrough__, for having a
  __attribute__((__fallthrough__)) statement that didn't immediately
  precede a case label.
