Regression in performance in statically linked modules

https://github.com/bytecodealliance/javy/pull/793 introduced a performance regression for statically linked modules because the QuickJS context no longer loads the JS module during pre-initialization. This is unfortunately an expensive step though not enough to trigger our fuel consumption checks in tests.

Some thoughts on how to go about this are to retain the QuickJS runtime in `compile_src` by wizening when performing that step or augmenting `initialize_runtime` to also optionally load source code or bytecode.
