Build recipes from a shared directory [DRAFT]

Ah, never mind – in its current state, it extracts another directory under recipes/numpy_shared_build/numpy-tests-2.2.3/, which evades the caching we need. I will need to revise it a bit.

Thanks @agriyakhetarpal. Please ping me when it is ready.

I wonder if we can utilize source.path field for this, by the way. It is used to building packages using the local files instead of downloading them from URL.

It was used for 1) testing purpose, 2) and when micropip was inside pyodide/pyodide, but I guess we can use it for sharing the build directories as well. For example, numpy packages downloads the archive from URL, and numpy-tests sets the path to the numpy's build directory.

Of course, this is a hack, and I am not sure it is good for the long-term solution, but I think is can be considered as an option.

This will be superseded by pyodide/pyodide-recipes#86, and should no longer be needed.
