Add seperate setting for NVG noise intensity

[BaerMitUmlaut]

When merged this pull request will:

• Add a seperate setting for NVG noise intensity

A seperate setting for this makes sense as it can cause headaches with long time use. The other effects do not cause this issue. Was also requested in #3594 by @ghost.

Should it not be a client setting in that case?

Should also be added via CBA Settings directly.

[BaerMitUmlaut]

No, because it's also a difficulty option.
I don't think it's a good idea to have half CBA, half ACE settings. Either convert all or none.

[jonpas]

Either convert all or none.

All, and use movedToSQF like in markers.

[BaerMitUmlaut]

That's not the point of this PR and should be done in a seperate one. Small, granular changes.

[jonpas]

Sure, but before next release then. Less movedToSQF the better. Doesn't matter during development as we obviously don't provide backwards compatibility that time.

[jonpas]

Looks good, but should be moved to CBA Settings directly (along with other settings in this component) before next release.

Not approving as I'd like @PabstMirror to take a look too.
