Currently, Intel's shader cache incorporates PCI ID into shader cache keys. Many devices with different PCI IDs have identical shader compilation functionality. Using PCI ID as a component of the shader cache hash means that a multi-platform shader cache will have redundant, identical entries for similar platforms. All Intel compiler functionality is selected based on device configuration in `struct intel_device_info`. intel_device_info.py flags all fields accessed by intel/compiler. This commit generates a hash function incorporating intel/compiler device info fields. Using this hash function in place of PCI ID will produce a multiplatform cache with no duplicated content.
