Don't blindly increase oversampling with NONLINEAR_EXTRUSION

[mh-dm]

Description

Don't blindly always increase oversampling with NONLINEAR_EXTRUSION. Just increasing oversampling can result in a stepper ISR rate higher than the microcontroller can handle, leading to hard to debug behavior.

While NONLINEAR_EXTRUSION does benefit from oversampling that does not mean it requires it to function. Let's take some common numbers as an example: 0.2mm layer height, 0.4mm line width, and 100mm/s speed. That's:

• 8000 steps/s for a motion axis (assuming we move just in X or just in Y at 80steps/mm)
• 8mm^3/s flow or ~3.3mm/s E speed assuming 1.75mm filament. E is usually 90-400 steps/mm so that's 300 to 1320 steps/s. Bresenham aliasing becomes a significant problem when the speeds differ by a factor of less than 3x and and we're looking at a 7-26x factor.

Benefits

Fixes #27163, see this comment for why.

This seems to have fixed the issue for me.
I happen to have the same electronics (SKR3) and settings you mentioned in the issue (NONLINEAR_EXTRUSION and ADAPTIVE_STEP_SMOOTHING).
The UI doesn't become sluggish anymore when moving.
Thank you!
