Title: Apply visual to some system app UI

### Wat this PR does ###
1. Modify list menu style
2. Modify modal dialog style
3. Create context menu test
4. Create multi web activities test

### Future work ###
1. Fix the multilevel context menu issues
(It's very very hard to invoke `mozbrowsercontextmenu` event now, I would file another issue about this)
