display/surface: add DEVICE_BITMAP_ALLOCATION_TYPE_RAM, cleanup surface alloc/free code paths
This adds a third surface allocation type, allocation from guest memory using
the windows ddk allocator.
Not all code paths are used later - the creation is not done since
copy-surfaces-to-ram allocates memory itself, and at the end we never allocate
any surfaces when the device is disabled, we just punt the allocation to the
gdi, but the code is still left in GetSurfaceMemory.
