FIX: when creating a canvas from a Figure use original dpi
When we upscale the DPI for high-dpi screens we stash the original dpi and thenset the figure dpi to the scaled version. If the same Figure instance isrepeatedly passed to a Canvas that support hi-dpi it would go into a loop wherethe scaled DPI is treated as the original dpi and infinitely increases.By grabbing `fig._original_dpi` (which we stash for exactly this reason) we canavoid this loop.closes#26380
