Bring back waveform for voice messages and retain seeking (#8843)

Browse source 
* Crude way of layering the waveform and seek bar

Not intended for production.

* Use a layout prop instead of something less descriptive

* Fix alignment properly, and play with styles

* Convert back to a ball

* Use `transparent` which makes NVDA happy enough

* Allow keyboards in the seek bar

* Try to make the clock behave more correctly with screen readers

MIDNIGHT

* Remove legacy export

* Remove redundant attr

* Appease the linter
