Support nvim lsp semantic token highlight

[rhcher]

Feature description

First, many thanks for your great work on this plugin. Now, nvim-bqf support two highlight solutions: coc semantic token and treesitter. I think it will be cool if we support nvim lsp semantic token in prevew window.

Describe the solution you'd like

impletion preview window highlight with nvim lsp semantic token api.
