mesa: Clamp some depth values in glClearBufferfi

OpenGL 3.0 spec, section 4.2.3 "Clearing the Buffers":

   depth and stencil are the values to clear the depth and stencil
   buffers to, respectively. Clamping and type conversion for
   fixed-point depth buffers are performed in the same fashion as for
   ClearDepth.

Enables iris to pass the clearbuffer-depth-stencil piglit test.
