Message:

Platform.h is out of control Part 4: Split PLATFORM_* macro definitions out of Platform.h and into a new PlatformLegacy.h
​https://bugs.webkit.org/show_bug.cgi?id=206272

Reviewed by Anders Carlsson.

As a another step towards cleaning up Platform.h, split out all the legacy platform
macros into their own file.
