refactor(drawing-tools): revert non-scaling-size

[eatyourgreens]

vector-effect: non-scaling-size isn't implemented in browsers, so this reverts it back to non-scaling-stroke in drag handles, point marks, and transcription lines.

Test cases in the dev classifier:

• point, line, and rectangle tools on a relatively small image: https://localhost:8080/?project=908&workflow=3370
• transcription lines on a relatively large image: https://localhost:8080/?project=mainehistory/beyond-borders-transcribing-historic-maine-land-documents&env=production

This PR shouldn't change how drawn marks are rendered at all. Points and drag handles should remain the same size and width, regardless of image zoom level.

Here's a quick codepen which draws two identical SVG circles, one with 'non-scaling-stroke' and one with 'non-scaling-size'. Stroke scaling is only ignored in the first. The SVG spec says that it should be ignored in both.

If you resize the SVG image, by resizing the browser window, you'll see that the righthand circle gets thicker or thinner, but the lefthand circle remains the same.

Please request review from @zooniverse/frontend team or an individual member of that team.

Refactoring

• The PR creator has described the reason for refactoring
• The refactored component(s) continue to work as expected

MDN: vector-effect is widely supported in all browsers since 2020.

Can I Use: non-scaling-stroke is widely supported. "Other values for the vector-effect attribute/property are currently at risk of being removed from the specification as they are not being developed by browser vendors."
