Web Inspector: Replace last use of ObjectPropertiesSection with ObjectTreeView
https://bugs.webkit.org/show_bug.cgi?id=142834

Reviewed by Timothy Hatcher.

* UserInterface/Views/DOMNodeDetailsSidebarPanel.js:
(WebInspector.DOMNodeDetailsSidebarPanel.prototype._refreshProperties):
Use properties only ObjectTreeView instead of ObjectPropertiesSection.
This doesn't fix the functionality issues, but fixes the appearance.

* UserInterface/Views/DetailsSection.css:
(.details-section > .content > .group:first-child > .row.simple:first-child > *): Deleted.
(body.mac-platform.legacy .details-section > .content > .group:first-child > .row.simple:first-child > *): Deleted.
(.details-section > .content > .group > .row.properties:not(.empty)): Deleted.
(body.mac-platform.legacy .details-section > .content > .group > .row.properties:not(.empty)): Deleted.
Re-add back the small padding at the top of sections. This actually
broke padding in a few sections (Event Listeners) at the expense
of eliminating a few pixels of whitespace at the top of other sections.
We should focus on addressing the extra whitespace separately.

* UserInterface/Main.html:
* UserInterface/Views/ObjectPropertiesSection.js: Removed.
* UserInterface/Views/TypePropertiesSection.js:
* WebInspectorUI.vcxproj/WebInspectorUI.vcxproj:
* WebInspectorUI.vcxproj/WebInspectorUI.vcxproj.filters:
Remove new unused class.
