Add WXWNDPROC typedef and use it in wxMSW instead of WXFARPROC

Browse Source 
WNDPROC and FARPROC are not the same thing in MSW and it's wrong to use
WXFARPROC as the type of different window procedures we use.

Introduce WXWNDPROC which is more clear and correct and use it instead.

Also get rid of a few casts which are not necessary any longer.
