Is your feature request related to a use case or problem? Please describe.

This is a follow-up to #7007, which reported qasm parser failure for identifiers starting with gate.
After the fix in #7018 the example code still fails because of unknown rzz gate.

Describe the solution you'd like

Support parsing of more QASM gates from "qelib1.inc".
At the very least we should add gates that have a direct counterpart in cirq.

What is the urgency from your perspective for this issue? Is it blocking important work?

P2 - we should do it in the next couple of quarters
