Allow configuring terminal position per project/workspace

[janlarres]

Body

What are you proposing?

At the moment the position of the terminal panel is a global setting, it is not possible to configure it per project. It goes so far that if I have two Zed windows/workspaces open and use the "workspace: move focused panel to next position" action then the terminal gets moved in both windows. This is undesirable as depending on various factors it may make sense to have the terminal in a different position for different projects. So it would be really useful to be able to configure the terminal position per workspace/project.

Why does this matter?

I use different window layouts depending on the project. For example for a web project I have Zed on the left and a browser on the right, and so it makes sense to have the terminal on the bottom for space reasons. With other projects I have Zed fullscreen and like having a permanent terminal on the right for various tasks. This is currently not possible to achieve.

Possible approach

Allow configuring the terminal position in the project settings file, and don't change the position in other windows/workspaces when changing it in one of them.
