DevTools: disable smoothing and correct nexus device frame dimensions for screenshots

For Nexus5X and Nexus6P presets, the existing SVGs were not well sized. That is:
height of device outline !== insets.top + screenSize.height + insets.bottom
This produced a noticeable gap in device mode screenshots. This CL corrects the
SVGs and insets to match measured dimensions.

Additionally, canvas drawn images look blurry in a device mode screenshots since
canvas contexts' imageSmoothingEnabled property is true by default. This CL
disables unnecessary smoothing.

Converted numbers to integers.  See the bug for an explanation as to why this
bug happens in screenshots but not device mode itself: crbug.com/652938

[dgozman, 2016-10-06 23:06:44]

The screenshots are still blurry for me, and Nexus 5X screens seems off by one
pixel.

[luoe, 2016-10-07 00:53:37]

That is correct, pixel adjusted after visual verification.
