When the V8 sandbox is enabled, ArrayBuffer backing stores must be allocated inside the sandbox address space. This change introduces a new CefV8Value::CreateArrayBufferWithCopy method that copies the memory contents into the sandbox address space. Enabling the V8 sandbox can have a performance impact, especially when passing large ArrayBuffers from C++ code to the JS side. We have therefore retained the old CefV8Value::CreateArrayBuffer method that references external memory. However, this method can only be used if the V8 sandbox is disabled at CEF/Chromium build time. To disable the V8 sandbox add `v8_enable_sandbox=false` to `GN_DEFINES` when building CEF/Chromium.
