This is a very early draft of what the transpiler C API will look like. It is very far from being able to compile and is missing some key pieces of functionality. But the goal of this early draft is to show what the transpile function will look like to inform how to design the rust interfaces of the individual passes.

This commit adds a Rust TranspileLayout object which is analgous to the Python space object. It is a self contained struct that is only for Rust and will be used by the C API for the C transpiler so that users will be able to reason about the permutations caused by the transpiler. This will also be used by Qiskit#14106 to apply a transpilation layout to the SparseObservable in C. This commit only adds the rust struct and it's associated tests, a subsequent PR will add the C API on top. This won't be used until we have a full path transpiler in C though (see Qiskit#14760).

Closes #14245
This is very much blocked until all the sub-issues on #14245 are implemented. This does not compile and won't be able to for sometime. It is still an very early draft to give a more concrete idea at what the final goal will look like.
