Navigation Link: Add "Open in new tab" toggle to navigation block sidebar

[Infinite-Null]

Fixes: #67246

What?

Adds the "Open in new tab" toggle option to the Navigation Link block's settings sidebar, making it accessible alongside other link settings.

Why?

Currently, the "Open in new tab" setting is only available within the link modal of the context menu, while all other link options are presented in the block settings sidebar. This inconsistent placement has confused editors trying to locate this commonly used option.

Thanks for getting on top of this, @Infinite-Null ! My only suggestion is that I feel the ToggleControl should be placed underneath "Link" rather than at the top of the Navigation Link block settings.
