Allow overrides of MI_DEBUG memory constants

Browse source 
CPython and Windows CRT debug builds use different values for uninit,
freed, and padding bytes. Make ``MI_DEBUG_*`` constants conditional to
allow embedders to override the constants.

Windows dbgheap:

```
_bNoMansLandFill = 0xFD
_bDeadLandFill   = 0xDD
_bCleanLandFill  = 0xCD
```

Python memory debug

```
PYMEM_CLEANBYTE      0xCD
PYMEM_DEADBYTE       0xDD
PYMEM_FORBIDDENBYTE  0xFD
```
