Qt: Scheduler tooltip fix

[xddxd]

The tooltip wasn't appearing on unsupported CPUs, tested on an i5 2500.

What's wrong with the current code?
I still a wanna see what this is

[xddxd]

In the current code when the combobox is disabled the tooltip doesn’t get changed from the one when it’s enabled.

[Megamouse]

It shouldn't. The tooltip in master is a popup.

[MSuih]

If TSX is disabled then the tooltip is changed in this way. I think it would be more consistant if scheduler behaved the same way

[xddxd]

This is what it looks like on master, when it should be like this:

[Megamouse]

No. I wanna know what this feature is.
Also, You didn't show the super obvious popup that comes when you hover on the option

[xddxd]

I wanted originally for it to change the description, not add a pop up. My mistake. facepalm. I’ll change the wording.

Maybe append the tooltip on master at the end. I think the warning about it being disabled should come first.

[elad335]

Ans if its not disabled show the text on master first instead but still show the warning at the end. So users won't be confused after changing CPU.
