Log:
- Remove all the remaining code in boot.S and make KiRosPrepareForSystemStartup fastcall. Now NtProcessStartup just does a jmp to KiRosPrepareForSystemStartup without any other code.
- Use freeldr's stack during all of freeldr.c, and only switch to the boot stack in KiSystemStartup before calling KiInitializeKernel. This is what NT does as well (it piggybacks on NTLDR's stack until then). This allowed us to clean boot.S and now we can boot from NTLDR properly.
