git: Replace file history view with git graph (#50288)

## Summary

This PR replaces the git file history view with the git graph view that
doesn't render the graph canvas. This has several advantages

1. Benefits from the graphs performance and lazy loading
2. Gets the graph's search for free
3. Resizable columns
4. The commit information panel
5. Is persistent 
6. Cleans up a lot of code

The one con of this change is the graph doesn't have support
remote/collab support yet, but that is a WIP and should be merged within
a week.

Also, the git graph now propagates errors to the UI, which is the last
thing on the graph's stable launch todo list!

Before you mark this PR as ready for review, make sure that you have:
- [x] Added a solid test coverage and/or screenshots from doing manual
testing
- [x] Done a self-review taking into account security and performance
aspects
- [x] Aligned any UI changes with the [UI
checklist](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist)

Release Notes:
