feature: support FreeParameter binding via make_bound_program

[laurencap]

Issue #, if available:
Closes #769

Description of changes:

Support make_bound_program

@aq.main
def my_circuit(main_argument: float):
    free_param = FreeParameter("alpha")
    rx(0, main_argument)
    rx(1, free_param)
    measure([0, 1])

my_circuit(3.14/2).make_bound_program({"alpha": 3.14}).to_ir()

The name and signature is patterned after make_bound_circuit. This name also helps inform the user that the method will make and return a new object, with the original left unchanged.

    def make_bound_program(self, param_values: dict[str, float]) -> Program:
    def make_bound_circuit(self, param_values: dict[str, Number], strict: bool = False) -> Circuit:

Testing done:

New unit tests

I like the API choice! Left a few minor comments, and also it would be good to get @jcjaskula-aws's opinion on the oqpy program manipulation here.

Adding some thoughts, if the IODeclaration does not need to be added in-place, we could investigate the use of _add_var.

Following up my comments, I'm proposing to explore something using _add_var.
