gl_device: Expose NV_vertex_buffer_unified_memory except on Turing

Expose NV_vertex_buffer_unified_memory when the driver supports it.

This commit adds a function the determine if a GL_RENDERER is a Turing
GPU. This is required because on Turing GPUs Nvidia's driver crashes
when the buffer is marked as resident or on DeleteBuffers. Without a
synchronous debug output (single threaded driver), it's likely that
the driver will crash in the first blocking call.
