mesa: add support for glUniformHandleui64*ARB()

Bindless sampler/image handles are represented using 64-bit
unsigned integers.

The ARB_bindless_texture spec says:

   "The error INVALID_OPERATION is generated by UniformHandleui64{v}ARB
   if the sampler or image uniform being updated has the "bound_sampler"
   or "bound_image" layout qualifier"."
