Telemetry: Remove unnessessary 'benchmark' traces.

We're moving towards 'benchmark' being only for traces that
are actually read by benchmarks, rather that part of
benchmarks. This changes several to 'input'. One is read by a
benchmark, so that is now 'input,benchmark'.

don't need to create SkBitmapDevice -- which is deprecated from the public API

this one file was lifted from https://codereview.chromium.org/184743002/ and then modified to erase the bitmap when it is not marked as opaque. This restores the previous behavior when we were explicitly creating SkBitmapDevice.

Fix Flash fullscreen context menu target and position.

This resolves two problems regarding the right-click context menu for Flash fullscreen widgets.  First, the WebContentsViewDelegate implementations (for Views and Cocoa) were assuming the event target for the context menu click is always the widget provided by WebContentsView.  Flash fullscreen is actually a separate widget.  Second, the renderer was trying to be "too smart" by computing the screen coordinates of the context menu itself.  This is fixed by removing the offset calculation, which allows the coordinates to be cleanly translated by the windowing toolkit, browser-side.
