Support for aliases for openqasm3 to qir

[ryanhill1]

In OpenQASM 3 the let keyword allows declared quantum bits and registers to be referred to by another name as long as the alias is in scope:

qubit[5] q;
// myreg[0] refers to the qubit q[1]
let myreg = q[1:4];

See https://openqasm.com/language/types.html#aliasing

Add support for converting OpenQASM 3 programs that use aliasing to QIR.
