Generate Rust client SDK from IDL file

[walkerlala]

Is it possible to generate an rust client SDK from an idl file, like what is done in anchorpy project (https://kevinheavey.github.io/anchorpy/), which can generate a python SDK from a provided idl file?

I know we can do it using the declare_program!() macro but the declare_program!() is still buggy now: #3490.
