TimelinePanel: initial implementation of FlameChart in TimelinePanel.

It works but doesn't support:
a) Details pane info for the selected item,
b) jump to function. We have no jumpable items at the moment.
c) zoom in the main FlameChart pane. It can be zoomed only via Overview pane.

Revert of Move quota module to oilpan (https://codereview.chromium.org/158133003/)

Reason for revert:
Broke the Oilpan build.

See: http://build.chromium.org/p/chromium.webkit/builders/WebKit%20Win%20Oilpan/builds/386/steps/compile/logs/stdio

Original issue's description:
> Move quota module to oilpan
> 
> This moves the storage quota interfaces to oilpan, using transition
> types.
> 
> Mostly regular, apart from one one interface (DeprecatedStorageQuota)
> being used from both a main world and worker context, requiring thread
> affinity defaults to be overridden for its class.
