intel/compiler: on MTL, DF instructions run in the math pipe

Browse Source 
Adjust the scoreboard code to take that into account.

Fixes at least:
  - dEQP-VK.glsl.builtin.precision_double.refract.compute.vec3
  - dEQP-VK.glsl.builtin.precision_double.matrixcompmult.compute.mat4

v2: use intel_device_info_is_mtl()  (Curro, Jordan)
