feat(lsp): highlight semantic token modifiers (#21390)

Browse Source 
Apply semantic token modifiers as separate extmarks with corresponding
highlight groups (e.g., `@readonly`). This is a low-effort PR to enable
the most common use cases (applying, e.g., italics or backgrounds on top
of type highlights; language-specific fallbacks like `@global.lua` are
also available). This can be replaced by more complicated selector-style
themes later on.
