Allow remapping of experimental.repositionCursorWithMouse to use key bindings such as Alt + Left Click

[digitalguy99]

Description of the new feature/enhancement

I'm aware that as of now, by setting experimental.repositionCursorWithMouse as true, we are able to move the cursor to the mouse's position with a simple left click. However, there are times when I want to simply click on the terminal to get it into focus without moving the cursor around. Hence, I think it would be best to let the user choose what keys would be best for them to utilize this feature, for eg. Alt+Left Click/Ctrl+Left Click/Middle Click.

Proposed technical implementation details (optional)

I'm aware that mouse key bindings are currently not available yet as explained in #1553. However, once they are available, I'd really love it if we can have a command such as moveCursorWithMouse and not just experimental.repositionCursorWithMouse as a profile setting just like how we have showContextMenu as a command that can be mapped to a key binding and not just the profile setting experimental.rightClickContextMenu.

So maybe we could have something like this in the future:

{ "command": "moveCursorWithMouse", "keys": "alt+left_click" }

thought: what if we just made it so a click that focuses the window doesn't attempt to move the cursor? I believe we already do that for selections (click-to-focus the window won't start a selection)

Good idea, is there a way to do that yet somehow?
But, anyhow, I think it'd be great if we could still choose the key binding especially since in iTerm2, Option+Left Click allows you to move the cursor to mouse position. Similarly, Alt+Left Click on the VSCode terminal would also do the same. I know some people would like to have the same key binding for every app to make it easier to remember.
