Adding stdgates.inc from https://arxiv.org/abs/2104.14722

Looks correct, but I think we should add this to the openqasm repository and then make qiskit dependent on that package. Also move parser there and just consume the AST here. What do you think?

I like the idea of having an independent package for openqasm. However, if we are talking about https://github.com/Qiskit/openqasm/ , that is not a package to depend upon. Are you talking about a different repo? If not, is there any plan to have an openqasm package? If yes, shall we wait for it or can we merge this one in the meanwhile?

Given that I've been thinking about/making editor plugins and a language server for QASM 2/3, I'm also +1 on having the QASM lexer/parser be a separate package that qiskit depends on. It'd let make a langauge server for it without reinventing the wheel or having the huge dependency on terra.
