Lock Screen Widgets: VoiceOver improvements

[staskus]

Grouping elements together so the widget information would be read out all at once. Otherwise, the elements on the widget are too small to properly interact with.

VoiceOver.Grouping.mov

To test:

1. Enable lockScreenWidget feature flag in FeatureFlag.swift
2. Open Jetpack, log into wp.com account
3. Add Lock Screen widgets
4. Enable voice over
5. Confirm that the information is read out clearly

Regression Notes

1. Potential unintended areas of impact

None

PR submission checklist:

• I have completed the Regression Notes.
• I have considered adding unit tests for my changes.
• I have considered adding accessibility improvements for my changes.
• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

UI Changes testing checklist:

• Portrait and landscape orientations.
• Light and dark modes.
• Fonts: Larger, smaller and bold text.
• High contrast.
• VoiceOver.
• Languages with large words or with letters/accents not frequently used in English.
• Right-to-left languages. (Even if translation isn’t complete, formatting should still respect the right-to-left layout)
• iPhone and iPad.
• Multi-tasking: Split view and Slide over. (iPad)

Verified that a VoiceOver tap now selects the whole widget and reads its contents in one go.
Thanks @staskus!
