Sifu and RDR break FEX's SMC tracking logic
Both Sifu and RDR break FEX's SMC tracking logic due to the ordering it does mprotects in. Nailed down where it is happening, now I just need to fix it.

small unittest which reproduces without running the full game.
```cpp
#include <cstdint>
#include <sys/mman.h>
#include <unistd.h>
#include <sys/syscall.h>

int main() {

  // Original:
  // Base: 0x6ffffc0b8000
  // PtrHigh: 0x6ffffc0be000 (+0x6000)
  // PtrLow: 0x6ffffc0bd000 (+0x5000)
  const uint64_t PtrBase = 0x10'0000;
  const uint64_t PtrLow = PtrBase + 0x1000;
  const uint64_t PtrLowSize = 0x2000;
  const uint64_t PtrHigh = PtrBase + 0x2000;
  const uint64_t PtrHighSize = 0x1000;
  const uint64_t TotalSize = PtrHigh + 0x1000 - PtrBase;

  (void)mmap((void*)PtrBase, TotalSize, PROT_NONE, MAP_PRIVATE | MAP_ANONYMOUS | MAP_FIXED, -1, 0);

  // Order matters.
  mprotect((void*)PtrHigh, PtrHighSize, PROT_READ);
  mprotect((void*)PtrLow, PtrLowSize, PROT_READ);

  ::syscall(SYS_exit_group, 0);
  return 0;
}
```
