To prevent any potential crash/OOM issues with "canvas" element
from "rogue" applications let's apply large size limitations for context
canvas2d's draw target to Servo (similar approach in Firefox/Chromium -
they limits width and height to 32767/65535 pixels).
Fixes: #36155, #34117, #30164, #24710
