Protect WebProcess::unblockServicesRequiredByAccessibility from attempting to
consume nullptr sandbox extensions
https://bugs.webkit.org/show_bug.cgi?id=268314
<rdar://121746329>
Reviewed by Per Arne Vollan.
The code in WebProcess::unblockServicesRequiredByAccessibility assumes that it
will always work with non-nullptr Sandbox Extensions. However, it's possible
for the SandboxExtension::create() method to return nullptr, so we should harden
this code to avoid crashing under such conditions.
