feat(acir_gen): Fold attribute at compile-time and initial non inlined ACIR

[vezenovm]

Partially resolves noir-lang/noir#4428 but not fully. Need ACVM execution work still.

This does the initial codegen work for having multiple ACIR functions.

It does a few things:

1. Adds a new InlineType that is now part of RuntimeType::Acir. We do not care about RuntimeType::Brillig as we do not inline any of those calls.
2. Fetch the appropriate function signatures for all possible Circuit functions inside of a Program. Previously we were just returning the main function signature. This is needed to accurately set up the private_parameters and public_parameters fields in a circuit.
3. Iterates over all SSA functions, determines which are entry points and codegens them
4. Codegens the newly added Call opcode from feat!: Acir call opcode #4773
