  Rename PLATFORM_IOS to PLATFORM_IOS_FAMILY
  
  The current define ANGLE_PLATFORM_IOS actually means
  "iOS or tvOS or WatchOS or MacCatalyst".
  The current define ANGLE_PLATFORM_WATCHOS means nothing.
  The current define ANGLE_PLATFORM_APPLETV means nothing.
  
  Replace PLATFORM_IOS and its uses with PLATFORM_IOS_FAMILY, so that
  then PLATFORM_IOS can be reintroduced and others can be fixed.
  
  Replace PLATFORM_IOS_SIMULATOR and its uses with
  PLATFORM_IOS_FAMILY_SIMULATOR for consistency.
  
  Use consistent `#if X` notation instead of `#if defined(X)`.
