fix(lsp): hide layout in codelenses in virtual text (#28794) (#28895)

Problem: layout i.e. whitespace that is part of codelenses is currently
displayed as weird symbols and large amounts of spaces

Solution: replace all consecutive whitespace symbols with a single space
character when trying to display codelenses as virtual text

(cherry picked from commit d9a2acdab3)
