Make Node.js language bindings context aware

[segevfiner]

They don't have any dynamic global data, so all it takes is just declaring them as such

We'll have to submit a PR with this change to all 113 of these: https://tree-sitter.github.io/tree-sitter/#parsers

Though possibly not all are active, I think there are somewhat more than 113.

Well if it comes down to it, we can always automate opening those PRs? Not sure how changes to the generation template or grammar generation were handled before. Not merging this and the accompanying PR to node-tree-sitter just means I'll have to fork and maintain patching everything by myself :(

More like 406. Most active parsers are desperately waiting for a new tree-sitter release to regenerate the grammar (which doesn't regenerate the bindings though).
