[ASan] [Windows] Avoid including windows.h in asan_malloc_win.cc

[mstorsjo]

Summary

Instead provide manual declarations of the used types, to avoid pulling in conflicting declarations of some of the functions that are to be overridden.

This is an alternative to D51879.

We can drop this define, it's just intended to reduce windows.h transitive includes.

Hm, these two constants are not as obvious as the typedefs. Oh well.

Doh, yes, will do.
