widl: Arrays should have freeing code generated on the server side, even if they are [in] parameters.

Fix the conditions under which pfnFree is called to only include arrays 
that will have been allocated, instead of being pointed to the buffer.

The native version of this DLL contains proxy code for various 
interfaces, but for the moment only servprov.idl is implemented.

sfnt2fnt: Use code from gdi32/freetype to do a better job finding the TTAG_EBLC to deal with older version of freetype without having to fall back on unreliable hacks.

comctl32/tests: InitCommonControlsEx() is missing on Windows 95 so call InitCommonControls() instead.

kernel32/tests: dll_capable() makes no sense since it's only used on APIs we link with. So remove it.
