Adds the stdlib side of issue freenet/freenet-core#2833, enabling delegates to create child delegates at runtime via a new V2 host function. Changes: - New error codes: ERR_DEPTH_EXCEEDED, ERR_CREATIONS_EXCEEDED, ERR_INVALID_WASM, ERR_STORE_FAILED - New extern block (freenet_delegate_management) with __frnt__delegate__create_delegate - DelegateCtx::create_delegate() ergonomic wrapper

Problem
Delegates cannot create other delegates at runtime. This is needed for use cases where a parent delegate needs to spawn child delegates dynamically (freenet/freenet-core#2833).
Solution
Add the stdlib-side API for the
create_delegateV2 host function:error_codesmodule:ERR_DEPTH_EXCEEDED(-20),ERR_CREATIONS_EXCEEDED(-21),ERR_INVALID_WASM(-23),ERR_STORE_FAILED(-24)freenet_delegate_managementWASM import namespace) with__frnt__delegate__create_delegateDelegateCtx::create_delegate()— ergonomic wrapper returningResult<([u8; 32], [u8; 32]), i32>(key hash + code hash on success)Resource limits enforced by the host side: max depth 4, max 8 creations per
process()call.Testing
