Add support for system-level `uv.toml` configuration (#7851) ## Summary Look for a system level uv.toml config file under `/etc/uv/uv.toml` or `C:\ProgramData`. This PR is to address #6742 and start a conversation. ## Test Plan This was tested locally manually on MacOS. I am happy to contribute tests once we settle on the approach. cc @thatch --------- Co-authored-by: Charlie Marsh <charlie.r.marsh@gmail.com>
