nvim: Add git conflict resolution mappings

Added simple merge conflict highlighting and resolution through
git-conflict.nvim plugin.

Allows moving to the next/prev conflict with ]x or [x respectively,
then resolving the conflict currently hovered by using ours/theirs/
both/or neither of the offered options (with `ho/hO/hm/hM`
respectively).
