Change title from "Skip All Breakpoints" to "Unskip All Breakpoints" when toggled

[HeikoKlare]

Current behavior:

In Windows 11 (see eclipse-platform/eclipse.platform.swt#501), when Skip All Breakpoints is off (deactivated)

... and when it's on (activated)

Expected behavior:

We should change the title to Unskip and possibly icon also.
Propose this and ask Ed Merks (mention him in [the original issue](see eclipse-platform/eclipse.platform.swt#501))

If possible, the icon of the menu (but not then one in the toolbar) should change to a check-mark, like the one in the menu Edit > Smart Insert Mode

The label could also be changed to a static "Toggle Skip All Breakpoints", similar to all the other options.

See eclipse-platform/eclipse.platform#864

I changed the state of this issue to Waiting because we need to check with Ed if the proposed solution is even acceptable (it would mean a "big visual change").
@ShahzaibIbrahim please check if the expected behavior (having different icons in the toolbar and in the menu) is even possible.

What was the result of checking with Ed?

Not good: eclipse-platform/eclipse.platform.swt#501 (comment)

At least he didn't reject it so it's up to us to decide.

I say we go ahead with the proposed solution and let the reviewers approve it or reject it. WDYT?
