A lot of the shared icons in toolkit/themes/shared/icons are being updated with a lighter stroke and Proton-y style. Devtools references some of its icons directly from chrome://global/skin/icons/*.svg. To avoid a mis-mash of old and new we'll need to temporarily create copies for use from chrome://devtools/skin/images/.

Backed out for causing build bustages.

Thanks. I wasn't sure how the allowed-dupes.mn worked. Looks like I need to list both sides of the duplication.

Thanks for the backout. I've identified the issue and devtools tests were passing so its re-pushed.
