WIN32: Fix pGetSystemWindowsDirectory found initialized during FcConfigParseAndLoadFromMemory
Trying to early loading a custom fonts.xml created on the
fly results in the pGetSystemWindowsDirectory function
pointer being found intialized. Normally the initialization
is performed in the default configuration loading.
The commit factorizes the lazy initialization of both
WIN32 getters (together with pSHGetFolderPathA) in a
function and call it when actually needed.
