[Qt][WK2] Pages / resources cannot be loaded from qrc files.

https://bugs.webkit.org/show_bug.cgi?id=107031

Reviewed by Jocelyn Turcotte.

Enables WebKit2 Qt applications to load files from the bundled
qrc files. This is achieved by adding a url scheme handler for
the "qrc" scheme using the application scheme handler and ignoring
all handlers for the qrc application scheme that the application might
set.
