Title: System value selector design fixes

### What is it?
As there is some work done in BB repo about upgrading some visual styles with value selectors, i've just applied these improves and also the markup decisions that has been taken from the PR done in to shared/style/.

### Main changes
* Removed old directory `system/style/bb/menus_dialogs/`
* Added new directory `system/style/bb/value_selector/`
* Added new file `system/style/bb/value_selector.css`
* Removed duplicated rules from `system/style/value_selector/value_selector.css`
* Now, these value selectors works covering the full view-port in the device (UX decision)
* Markup changes for more semantic and friendly aria role.
* Adapting the JS to the markup changes
