Add support for wgsl directives. (#123)

I started down the path of allowing imports to also be able to define directives that then get merged and validated when composing the final module, but this started to get too complicated and since this is already pretty niche just went with top level modules being able to declare directives. A lot of that is still there though if someone wanted to implement. --------- Co-authored-by: Elabajaba <Elabajaba@users.noreply.github.com>
