Fixes #10095
Fixes #10083
Fixes #9485
fixes #9177
Fixes #5326

Summary of the issue:

Aria role grouping is not conveyed by NVDA. This also applies to other grouping types, like fieldsets and figures.

Description of how this pull request fixes the issue:

Added the ability to report groupingsin browse mode. It can be disabled using the document formatting category of NVDA's settings. Groupings are only reported when they have a label, legend or caption.

Testing performed:

Tested several examples from the issues listed above.

Known issues with pull request:

1. Edge tends to classify objects as groupings much more often than IA2 based browsers do. Some wider testing in Edge is required to find out whether this is annoying.
2. Figures are still reported as groupings. We should decide on whether to add a new figure role, map this to graphic or diagram, or leave this as is (grouping).

Change log entry:

• New features

This now also adds the figure role for now, as I remembered I had some code that already did this. Note that this pr touches the same code as in #10424, so probably best to Finnish #10424 first.
