Remove dependency between PageAllocator and platform.

We move away from cryptographicallyRandomValues() and onto a simple built-in
random generator.

Remove excessive indentation in HTMLElement.idl

It's been like this for a long time for no apparent reason, and
is harder to read (and fit on screen) than it needs to be.

Bump the severity of blocked mixed content from Warning to Error.

No tests change based on this, as we don't currently emit the message's
level in WebTestProxyBase::didAddMessageToConsole. That's probably
worth changing, but it will be a pain in the ass to rebaseline all the
results.
