fix: High cpu usage on O-PENDING mode 

Mitigation for #967

This happens primarily because of
https://github.com/neovim/neovim/issues/22263

To prevent this from affecting lualine. Mode changed event
for op-pending mode no longer gets scheduled.

As a side effect lualine no longer properly refreshes upon switching
to op-pending mode.
