intel/blorp: Add a shader type to make keys more unique

Browse Source 
Depending on how the driver using blorp implements its shader caching,
there is a small chance of shader collisions due to identical keys between
blit and clear programs.  Adding a small shader type at the top of the key
alleviates this problem.
