-----------
Speculative preload scanner incorrectly preloads scripts inside SVG elements
https://bugs.webkit.org/show_bug.cgi?id=313589
rdar://175800116
Reviewed by Chris Dumez.
This patch aligns WebKit with Gecko / Firefox.
SVG scripts use href/xlink:href, not src. The preload scanner
now tracks SVG depth via m_foreignContentCount and skips script
preloading when inside SVG foreign content.
