Ensure all iframes are sized correctly at creation
Following in the path of #22395, these commits serve several purposes:
* prevent layout instability early during iframe loads caused by a succession of resize events
* reduce the complexity of determining what actual DPI and initial window size values are being used at startup
* ensure that all documents have a correct initial viewport size at creation
These changes fix problems that were exposed by the changes in #24462 but are independent of that PR.

Print an error if Glutin port needs to manage a new tab
When a tab needs to be created because the user clicks on a link with a `target=…` attribute, the Glutin port just ignores it, creating weird behaviors.
We should at least print an error.
