Print all builtins in the error message of inter-stage shader variables

This patch adds all the used built-in variables in the error message
of the violation of maximum inter-stage shader variables. With this
patch the error messages will be as below:

- Total vertex output variables count (17 = 17 (user-defined)) exceeds
  the maximum (16).
- Total vertex output variables count (17 = 15 (user-defined) + 2
  (clip_distances)) exceeds the maximum (16).
- Total fragment input variables count (17 = 17 (user-defined)) exceeds
  the maximum (16).
- Total fragment input variables count (17 = 16 (user-defined) + 1
  (front_facing) exceeds the maximum (16).
- Total fragment input variables count (17 = 16 (user-defined) + 1
  (front_facing|sample_mask) exceeds the maximum (16).
- Total fragment input variables count (17 = 16 (user-defined) + 1
  (front_facing|sample_mask|sample_index) exceeds the maximum (16).
