Fenix: Show the download progress size in kB, MB, GB, etc. instead of percentage

[ghost]

Currently Fenix doesn't show the download size but instead shows the percentage and a progress bar with respect to how much the file has been downloaded but if Fenix showed the download size in kB, MB, GB, etc. and it's progress like how Chrome browser does it. It'll be really helpful.

For example the file has downloaded;

3 kB / 500 kB, 20 MB / 500 MB, 1GB / 10 GB and so on...

See the screenshots for clarification.

UNITO-UNDERSCORE!20200707!UNITO-UNDERSCORE!210144!

P.S. To be really honest until now I always thought that Fenix did this but after trying to get the screenshots for filing this issue I realized that it isn't the case. I thought that only in this issue https://github.com/mozilla-mobile/fenix/issues/11107 the file size is not being shown but after seeing it now I realized Fenix doesn't do this; it doesn't show file size at all; it only shows a progress bar and a percentage in the notification. It really caused a lot of confusion between me and the developers, wait, actually it was just me who was confused. Sorry... :grinning:
This confusion caused because I mostly use external third-party download managers, so I download files very rarely with Fenix. I always thought that how could Fenix be missing such an useful feature. Or so...

CC @Amejia481 I have filed the new issue for download size progress in the notification bar instead of a percentage. Is it correct? Does clearly conveys the idea of what we were talking about?
