Space is reserved when there is no label shown, creating a large unnecessary white space

[martyf]

Bug description

This is a Group fieldtype, with the Display Label turned off. "Text Field" is a child of the Group.

The rendered markup includes the sr-only markup for the Label, but there are two margins added: one is mb-2 in the Field.vue, and the other is a mb-1.5 in the Label.vue (See #14710).

If a Label is not shown, it should not have elements that take up visible space: basically it means that a Field without the Label shown will have a 8px extra gap above it.

For example:

I've looked in to a PR for this but is challenging because at the Field level it is not able to cleanly determine whether the Label will actually render any content or not.
