UI: Bring back hover shortcuts for mesh modifiers

Earlier last year, the shortcuts on hover were built as a way to regain
speed lost by removing the "Apply" and "Copy" buttons from the panel.
For the active modifier concept introduced for geometry nodes, the
shortcuts were changed to only affect the active modifier.

Based on feedback, this change slowed down many people's interaction
with the modifier stack so the UI team decided to return hover shortcuts
for modifier panels.

The downside of this change is that it looks like the active modifier is
"selected" and it could be confusing that the modifier shortcuts don't
apply to it. We can explore different ways to display the active status
to address this.
