feat(fold): transparent foldtext

Browse Source 
'foldtext' can be set to an empty string to disable and render the
line with:
  - extmark highlight
  - syntax highlighting
  - search highlighting
  - no line wrapping
  - spelling
  - conceal
  - inline virtual text
  - respects `fillchars:fold`

Currently normal virtual text is not displayed
