[WIP] View based refactoring in workspace v2

[gerblesh]

Rebased and modified from the original author: #4381
As is disclaimer this is heavily WIP and I'm fairly new to Rust so things aren't the cleanest

A couple changes:

• It also now uses the global_search command rather than bespoke query logic
• Keybind to put the results from the search into the refactor buffer is (ctrl-q). The keybind is mainly because of vim muscle memory so it's subject to change
• The global_refactor command still exists as a way to "write out" the changes to the buffers, though I think it might be nice to eventually make it work on the :write command

This is also still using the enum in Document since using View (seems) to require much deeper knowledge of Helix's codebase and rewriting/reusing much of the document editing code.

This PR is mainly meant to document my changes but feedback/reviews are welcome, though I don't expect this to be merged, especially as-is. This might also be better suited as a plugin

ok so I modified the gutter to display the custom path but I'm not sure how I feel about touching so many internals of Document and Gutter and putting down a bunch of match statements. It feels a little tacked on atm, though anything cleaner seems to be a lot more work that would require restructuring. Ideas and feedback are very much welcome on how to improve this implementation

Here's a demo using now with the gutter being "properly" implemented

Hi, I was looking into this and it looks super cool and very similar to oil.nvim. However at the moment the global_refactor is not a typed command i.e what if I am inside a workspace and I would like to perform a refactor inside specific directory or a file? Something like ":refactor x/y/z".

currently the way to specify a directory is to use the column matching in the global search picker so something like <regex> %p <filepath> and then ctrl+q, not perfect though, maybe there's a simple change to global search that allows searching just within a certain filepath as well. The global_refactor command does not open or search regex anymore, it simply writes out the changes of a refactor buffer
