Remove check for block sizes when using a compiler

[isazi]

In tune_kernel there is a call to check_block_size_params_names_list that produces a warning if you don't have e.g. "block_size_x" in your tunable parameters. This is not useful when not using CUDA/HIP, and should not be checked. A possible solution could be based on the value passed to the lang or compiler arguments, such as skipping the test if the user is specifying its own compiler.
