Per stage headers, ghc_boot_platform.h -> stage 0 ghcplatform.h
The generated headers are now generated per stage, which means we can skip hacks like `ghc_boot_platform.h` and just have that be the stage 0 header as proper. In general, stages are to be embraced: freely generate everything in each stage but then just build what you depend on, and everything is symmetrical and efficient. Trying to avoid stages because bootstrapping is a mind bender just creates tons of bespoke mini-mind-benders that add up to something far crazier. Hadrian was pretty close to this "stage-major" approach already, and so was fairly easy to fix. Make needed more work, however: it did know about stages so at least there was a scaffold, but few packages except for the compiler cared, and the compiler used its own counting system. That said, make and Hadrian now work more similarly, which is good for the transition to Hadrian. The merits of embracing stage aside, the change may be worthy for easing that transition alone.
