This does this following things: - Default to the runtime automatic number of threads for pre-compiling shaders - Adds a distinct automatic thread count computation for pre-compilation (which has less other things going on and should scale better beyond 4 cores) - Removes the unused logical_core_count field from the CPU detection - Changes the semantics of num_cores from maximaum addressable number of cores to actually available CPU cores (which is also how it was actually used) - Updates the computation of the HTT flag now that AMD no longer lies about it for its Zen processors - Background shader compilation is *not* enabled by default
