What is the bug or the crash?

Any symbol's interpolated line layer will fail to render anything when used with a layout polyline item or a line annotation.

Steps to reproduce the issue

  1. Create a new layout
  2. Add a polyline item
  3. Edit its symbol, set the symbol layer to 'interpolated line'
  4. Notice it failing

Interpolated line renderer: don't assume that a feature is available

Instead we should ALWAYS use the provided points for rendering symbol
layers, or the symbol layer will be broken in various circumstances
(e.g. when used outside of a vector layer)

Fixes qgis#45028
