Treesitter for meson build

It just works, for highlight in neovim

if comment in some where, the Treesitter will break

about the base types and command

if else and loop

operate

Better handle of comment, maybe need scanner.c, but I am not good at c

I need more tests

please give the issues, I will try to fix

Take it as a reference and make a new one

I don't think it can be used to make lsp or format.. It is bad
