feat: add lsp hl groups from upstream, tidy up tree-sitter hls (#330)

* chore: remove commented deprecated groups

* feat: add rule-based sem token highlighting (tracking 1cc23e1109)

* feat: add ts-rainbow2 highlights

* feat: add special string documentation highlight, remove unused group, and reorganize hl groups based on nvim-treesitter

* fix: linked to treesitter groups and added some additional missing hl groups
