uv/tests: adds a test with mutually exclusive extras across a workspace
This tests comes from here: https://github.com/astral-sh/uv/pull/8976#issuecomment-2473672199 And it was originally thought of by Konsti. This test case is the motivation for making `package` optional in `conflicts` instead of forbidding it entirely.

Because proxy1[project1]==0.1.0 depends on anyio==4.1.0 and proxy1[project2]==0.1.0 depends on anyio==4.2.0, we can conclude that proxy1[project1]==0.1.0 and proxy1[project2]==0.1.0 are incompatible.

And because we know from (1) that dummy[project2] depends on proxy1[project2]==0.1.0, we can conclude that dummy[project2] and proxy1[project1]==0.1.0 are incompatible.

And because only proxy1[project1]==0.1.0 is available and dummysub[project1] depends on proxy1[project1], we can conclude that dummysub[project1] and dummy[project2] are incompatible.

And because your workspace requires dummy[project2] and dummysub[project1], we can conclude that your workspace's requirements are unsatisfiable.
