Allow skip wheel installation in maturin develop command

[messense]

When using maturin together with Poetry in a monorepo, one can add Rust Python binding project as an editable module to Poetry dependencies, like

[tool.poetry.dependencies]
rust-project = { path = "rust-project", develop = true }

It works great with poetry install --sync, and for mixed Python/Rust project layout, when Python code changes there is no need to run poerty install again, it just works.

But when Rust code changes, poetry install --sync doesn't rebuild rust-project, so you have to use maturin develop instead, unfortunately while maturin develop makes the Rust code change visible, it causes poetry install --sync to rebuild rust-project again because Poetry thinks the dependency has been changed.

I think we can add an option to maturin develop command to skip wheel installation step, only build the extension module inplace, similar to #1419.
