RwRasterRenderFast: Expand supported types

[SK83RJOSH]

Found this while working with render targets (rwRASTERTYPECAMERATEXTURE); it currently only supports copying from rwRASTERTYPECAMERA.

It appears that it should support all available raster types based on:
https://github.com/GTAmodding/rw37/blob/master/src/driver/d3d8/d3d8raster.c#L1469
https://github.com/GTAmodding/rw37/blob/master/src/driver/d3d9/d3d9raster.c#L1591

The only problem I see with this, is that we'll have to use the slower glCopyImageSubData instead of glCopyTexSubImage2D. Though we can probably limit that just to the types that require it, and avoid any functional changes.

For reference:

librw/src/gl/gl3device.cpp

From the RenderWare Userguide:

" RwRasterRenderFast(), performs a faster blit operation, but takes no
account of the alpha channel. This makes it considerably faster on most
platforms. "

This also causes me a bit of concern, as I know direct way to do this kind of operation in GL without taking into account alpha. So feedback welcome on that bit. :)
