Fixes scrolling in lazygit, less, htop, man...

If you open lazygit and try to scroll the code changes using a high res mouse (e.g. MX Master 3S). It does not scroll unless you scroll super fast. It's because the scroll even comes in and since the amount is less than a line, it gets rounded down to 0, instead getting accumulated.

The issue with less was that we always were sending normal-mode sequence b"\x1B[A", but less sets application cursor mode and expects b"\x1bOA".

I had to move report_mouse_wheel_as_arrows to the terminal.rs to keep Rust happy since we need mutable access to the terminal and the terminal's mouse_reporter.
