[maybe split into more granular tasks]

  1. move the global state back to Include/internal (see below)
  2. move PyRuntimeState.obj to PyInterpreterState.obj
  3. move PyRuntimeState.mem to PyInterpreterState.mem

Notable concerns:

  • very delicate code
  • allocators needed before main interpreter created (?)
  • keep a global allocator?

The global state for this was moved back out of Include/internal to fix a bug. That PR encapsulates the relevant global state and C-API pretty well.
