feat(lspinfo): replace :LspInfo with :checkhealth #3339

Problem:
:LspInfo has its own "inner platlform" of highlights, mappings etc. And
it doesn't integrate with :checkhealth.

Solution:
- Move the lspinfo code to a healthcheck.
- LspInfo features such as highlights, "floating window" presentation,
  etc., should be added to :checkhealth in Nvim core, if they are really
  needed.
- Define a "q" mapping until Nvim stable has that in :checkhealth.
