[libclc] Move log2/log10 tables to CLC tables impl

These two tables were being used by the CLC library but their
definitions still remained in the OpenCL layer. This worked out after
linking the two together but is a layering violation.

This had a side effect of removing the two table getters from the final
bytecode library, which were never intended to be exposed.

These two tables should probably be refactored so allow better
vectorization of log/log2/log10, but that is left to future work.
