Description: We have a client that is using this tool to verify the validity of their website (I explained more about this tool on LPS-133314) The tool seems to not like this CSS rules that starts with * made specially for fixing IE7 issues

We need to remove this rules same like in LPS-135072

Steps:
1. Start bundle and open this CSS file /o/frontend-css-web/main.css
3. For example, check in this file for rules that start with "*padding", "*height", "*width" ...

Actual: There are CSS files that contain rules that start with *, these rules are fixes for IE7 that we don't support anymore, and it should be removed as we have clients that complain about their accessibility tests failing cause of it. 

Expected: There are no more rules starting with * in/o/frontend-css-web/main.css and /o/frontend-css-web/portal/aui_deprecated.css file
