meson: Check for SPIRV-Tools and llvm-spirv

Browse Source 
Changes since:
* v12 (Karol Herbst):
  - rename CLOVER_ALLOW_SPIRV to HAVE_CLOVER_SPIRV
* v11 (Karol Herbst):
  - only set new defines for clover to speed up recompilation
  - remove autotools
* v10:
  - Add a new flag (`--enable-opencl-spirv` for autotools, and
    `-Dopencl-spirv=true` for meson) for enabling SPIR-V support in
    clover, and never automagically enable it without that flag. (Dylan Baker)
  - When enabling the SPIR-V support, the SPIRV-Tools and
    SPIRV-LLVM-Translator libraries are now required dependencies.
* v7:
  - Properly align LLVMSPIRVLib comment (Dylan Baker)
  - Only define CLOVER_ALLOW_SPIRV when **both** dependencies are found:
    autotools was only requiring one or the other.
* v6: Replace the llvm-spirv repository by the new official
      SPIRV-LLVM-Translator.
* v4: Add a comment saying where to find llvm-spirv (Karol Herbst).
* v3:
  - make SPIRV-Tools and llvm-spirv optional (Francisco Jerez);
  - bump requirement for llvm-spirv to version 0.2
* v2:
  - Bump the required version of SPIRV-Tools to the latest release;
  - Add a dependency on llvm-spirv.
