Multiple labels for the Library Settings Editor ou selector

[Jane Sandberg]

On today's main, the Library Settings Editor has two labels for the OU selector.

Steps to recreate:
1. Go to an Evergreen that has the main branch or rel_3_12 branch loaded.
2. In the staff client, go to Administration > Local Administration
3. Choose Library Settings Editor
4. Note that there are two labels for the org unit selector, "Context Location" (in grey) and Library (above the selector).

Success criteria:

* There is only one label for the org selector on this screen.
* The label is associated with the selector (currently, the "Library" label is, but the "Context Location" label is not). See https://wiki.evergreen-ils.org/doku.php?id=accessibility:forms:labels for more details.

The org selector in the Angular circulation patron details screen is also missing its visible label.

The new labeling method I introduced in bug 1999158 turned out to be very incompatible with some screens that have a complicated labeling strategy, like the patron edit form in Angular Circulation. I saw no good way to make it work except to revert to using ARIA labels, as we do in many other components. This makes for a difficult branch to review, since we have such a mixed label strategy for org selectors and the changes affect every single one.

I have checked all of the screens I could think of and I no longer see any duplicate visible labels with this branch applied.

Signed off and merged for inclusion in 3.12.
