[WIN32K]

A bit of code reorganization:
- move a maximum of typedefs into their corresponding headers,
- move user heap functionality into a dedicated header,
- add a note in some functions that the first heap mapping entry in the W32 process info structure is dedicated for the global user heap mapping,
- remove extra-parenthesis in casts.
