headers: Remove a duplicate declaration of GetFileType

This function isn't available in WINAPI_PARTITION_APP like all
the other ones surrounding it, but this function also already is
declared further above in the same file, in an

    #if WINAPI_FAMILY_PARTITION (WINAPI_PARTITION_DESKTOP) || _WIN32_WINNT >= _WIN32_WINNT_WIN10

block. (The function was in WINAPI_PARTITION_DESKTOP in Windows
8.0 but was moved to WINAPI_PARTITION_APP in Windows 10.)
