intel-graphics-compiler should link against the Khronos SPIRV-LLVM-Translator instead of the unsupported built-in translator

Description:

Currently the Arch Linux intel-graphics-compiler package is built with the built-in SPIR-V translator instead of the Khronos SPIRV-LLVM-Translator. The built-in translator is not supported according to upstream developers and appears to be broken, as seen in the same upstream issue.

The intel-graphics-compiler should be rebuilt with the IGC_OPTION__LINK_KHRONOS_SPIRV_TRANSLATOR and IGC_OPTION__USE_KHRONOS_SPIRV_TRANSLATOR_IN_SC options set to ON (i.e. their default value).

Additional info:

• package version(s): intel-graphics-compiler 1:1.0.17537.20-1
• config and/or log files: See upstream bug report.
• link to upstream bug report, if any: https://github.com/intel/intel-graphics-compiler/issues/345

Steps to reproduce:

See upstream bug report.
