Avoid an occasional null deref under
Quirks::advancedPrivacyProtectionSubstituteDataURLForScriptWithFeatures

Reviewed by Aditya Keerthi.
Add a null check and bail in
`advancedPrivacyProtectionSubstituteDataURLForScriptWithFeatures`, in
the case where the `CodeBlock`'s owner executable is null. Currently, we call
`source()` to grab
the corresponding `JSC::SourceCode`, which assumes that `m_ownerExecutable`
exists (which isn't
always the case).
