Detect presence of dwrite_1.h.

This introduces the SK_HAS_DWRITE_1_H define which may be set at
build time or will be true when WINVER_MAXVER >= 0x0602 .

The dwrite_1.h header is available starting in Windows SDK 8.0.
This change supports users who must still use Windows SDK 7.0.
It also allows for easier local testing of the older interfaces
on newer versions of Windows.
