feat(ext_messages): add hl_id to ext_messages chunks

Browse Source 
Problem:  Ext_messages chunks only contain the highlight attr id, which
          is not very useful for vim.ui_attach() consumers.
Solotion: Add highlight group id to message chunks, which can easily be
          used to highlight text in the TUI through nvim_buf_set_extmark():
          hl_group = synIDattr(id, "name").
