Remove initiallyFitToViewport attribute
https://bugs.webkit.org/show_bug.cgi?id=102392

Reviewed by Noam Rosenthal.

Remove the initiallyFitToViewport which shouldn't have been
added in the first place. We now reset userScalable to auto (-1)
in case it was not explicitly set by the web author.

Same behavior, covered by existing tests.
