Web Inspector: eliminate the linear and rendering frames TimelineOverview subclasses

• Component: Web Inspector
• Status: RESOLVED FIXED

[Matt Baker]

* SUMMARY
Eliminate the linear and rendering frames TimelineOverview subclasses. TimelineRecordingContentView maintains two separate overviews, and switches between them depending on the view mode (Timelines vs Rendering Frames). This seems overly complicated, since the two subclasses only differ in the settings they provide (selection, zoom level, ruler snapping, etc). TimelineOverview should encapsulate the ViewMode, rather than the sidebar, and maintain settings for each mode.

This change is motivated in part by https://bugs.webkit.org/show_bug.cgi?id=153034. Moving the timelines tree outline into the overview is made more awkward by the existence of two separate overview classes.

_timelinesViewModeSettings would read better than two plural nouns.

_renderingFramesViewModeSettings

Could make this the default assignment for the let, and just keep the if without an else.
