Adds a with-minimap class on the pane view
Replaces the minimap editor build with EditorView methods

The `EditorView` class already provides us with methods to
generates the lines html. It’s not only faster ; generating the minimap
for a ~200 lines file goes from 65ms down to 15ms without any other
optimization ; it also allow us to benefit from the soft wrapping
settings of the editor view without hassle. The minimap now completely
match the editor view in content.
Adds a wrapper between the minimap and its content

It will allow to separate the positioning of the minimap and the
scaling/transformation of its content. It’ll also allow to not depend
on the editor view state in transform computation (we’ll only rely on
the minimap content)
 Adds a margin on the editor scroll view to fit the minimap in

The goal here is to have the minimap taking 10% of the pane, the editor
scroll view and the scrollbar are moved 10% from the right border to
mimic the ST behavior where the buffer doesn’t run behind the minimap.
Removes width and translation transform on minimap

The minimap is now positioned using css only
Improves minimap overlay positioning

There’s still a problem with the minimap scroll though.
