This commit adds the following gates specified in the OpenQASM 3.0 specification: SDG, T, TDG, SX, SXDG, CY, P, U, CP, CRX, CRY, CRZ, CU, CSWAP, and GPHASE. Support for GPHASE is currently limited: the gate is ignored by the circuit simulator and the transpiler. It is useful, however, to have it internally in order to add control to the decompositions of the other gates. Additionally, this commit adds the CJ gate, which is useful internally for adding control to decompositions that involve J gates. These additions were motivated by the issue TeamGraphix/graphix-qasm-parser#14. The OpenQASM parser plugin can now parse all the gates and map them to native Graphix gates without translation, except for `u1`, `u2`, and `u3`, which are maintained for compatibility with OpenQASM 2.0 and are translated.

This commit adds support for all the gates specified by the OpenQASM 3.0 specification that were previously missing: SDG, T, TDG, SX, SXDG, CY, P, U, CP, CRX, CRY, CRZ, CU, CSWAP, and GPHASE. These gates are also added natively in Graphix in TeamGraphix/graphix#592, eliminating the need for translation. The gates u1, u2, and u3, which are retained for compatibility with OpenQASM 2.0, are translated.
