directwrite: support WinRT/UWP, which forbid LoadLibrary
Normally, we delay loading Dwrite.dll until runtime to allow building
and running DirectWrite-enabled libass binaries on old Windows versions
that lack DirectWrite. However, this is forbidden in WinRT/UWP.
DirectWrite is present in all versions of Windows that support WinRT/UWP,
so we lose nothing by requiring it.
Older Windows SDKs (Microsoft and MinGW alike) lack <winapifamily.h>,
so include it only if we really need it.
Based on VLC patch for libass:
https://github.com/videolan/vlc/commit/eedb57aa96d2bc0046a6da2e081c75ae9edf8fd5
and on this autoconf code:
https://github.com/lu-zero/mfx_dispatch/commit/c51a54c15f51579804030c70592c0a26065f1242
Note: the VLC patch retained an unconditional call to FreeLibrary
in destroy_provider. However, FreeLibrary does not actually expect
NULL as argument, so this commit adds a guard to that call.
Perhaps FreeLibrary(NULL) simply fails cleanly and that's why
this has not caused VLC problems, but we should not rely on this.
