hyprctl: add modkeys to binds command

[davc0n]

Describe your PR, what does it fix/add?

#8606

Is there anything you want to mention? (unchecked code, possible bugs, found problems, breaking compatibility, etc.)

No

Is it ready for merging, or does it need work?

Ready

[vaxerski]

isn't that just duplicating info

[davc0n]

Not sure, that's the current output:

binde
	modmask: 65
	submap: 
	key: l
	keycode: 0
	catchall: false
	description: 
	dispatcher: moveactive
	arg: 20 0

There would be an additional line: modkeys: SUPER SHIFT
This information is not directly available.

Or do you mean it should be computed on the fly, rather than stored in SKeybind ?

[vaxerski]

This information is not directly available

it is. See modmask.

[davc0n]

With direct I meant explicit.
Must remember which keys belongs to the given code.

Anyway if you believe that's useless just close this PR and the related issue as not planned.
