No support for mouse events

[luisjakon]

Describe the bug

When installing vim-tpipeline alongside Zeioth/heirline-components.nvim you can no longer click on the the clickable components such as git_branch, git_diff, diagnostics, lsp, etc. for quick access to info and actions.

To reproduce

1. Install vimpostor/vim-tpipeline
2. Install zeioth/heirline-components.nvim
3. Configure heirline statusline with any component implementing on_click

Expected behavior

Statusline components should behave normally with clickable sections

Yeah, right now the vim->tmux bridge does not implement translation of click events.
The tmux mouse support is also not really the greatest (read MOUSE SUPPORT in man tmux(1)), meaning this one is a tough one to implement. It requires the translation from tmux mouse_x, mouse_y location back to the statusline components and on top of that some architectural changes to communicate back to vim (previously every feature only required unidirectional communication).

It's not a lot of work, but still the work needs to be done. For me personally the feature is not really of importance as I have never used the mouse in vim, but I would be willing to merge a PR.
