Codicons: Preserve smaller icons

[why]
The codicons have 3 obvious (from the name) pairs of regular and small
icons. The size difference is slight but visible.

When we maximize all individual icons the differences are mostly lost.

[how]
Put each pair into one ScaleGroup to keep their individual scaling.

Fixes: #1214
