virtual/opencl: add dev-libs/ocl-icd as the fallback provider
Advantages:
* keyworded x86
* supports multilib on amd64
* all OpenCL-aware software should compile and link fine against it
* should make it easier for user to deploy out-of-tree OpenCL
providers (side note: all actual OpenCL providers currently
in the tree except x11-drivers/nvidia-drivers actually *require*
this to work), should they choose to do so
Disadvantages:
* essentially a hack to ensure the integrity of the dependency tree
on x86 and amd64/abi_x86_32 - most of the actual OpenCL providers
currently in the tree are 64-bit only anyway
