Bug: Inconsistent rendering of line caps between GraphicsLayer and FeatureLayer

[dpocius]

Describe the bug When the line is rendered in GraphicsLayer, line caps are rendered as round. When the same line is rendered using FeatureLayer - same line caps are rendered as butt/square.

To Reproduce Steps to reproduce the behavior:

1. Go to https://jsbin.com/sadewufibi/edit?html,output
2. Observe that line caps are rendered as round in GraphicsLayer (e.g. most bottom part, u-turn case)
3. Go to https://jsbin.com/qazikoqaja/edit?html,output
4. Observe that the same line caps are rendered as butt/square

Expected behavior Result of rendering same line in GraphicsLayer and FeatureLayer should be equal

@dpocius the differences you see are due to some additional processing we have enabled for graphics. Due to time processing constraints, we currently do not apply this logic in the case of FeatureLayers or VectorTileLayers. This is a known limitation for now and we are looking at ways to improve this area and speed up mesh processing.
