  [GTK][WPE] font-size-adjust:0 and SVG Font failures
https://bugs.webkit.org/show_bug.cgi?id=290449

Reviewed by Carlos Garcia Campos.

If the given font lacks the required glyphs, a system fallback font is created.
Previously, the fallback font was initialized with the computed size, which 
caused
failures in tests using font fallback with font-size-adjust. To fix this, we now
apply font-size-adjust when setting the size of the fallback font.
