Fixes a crash that happens when calling postMessage on an empty typed array. GetBuffer should only call MaterializeArrayBuffer for on-heap buffers, but the on-heap check is slightly wrong. This CL moves the on-heap check logic to the JSTypedArray class so that other parts of the codebase don't need to worry about how that is determined. Also add some dchecks to materialize itself. It should only receive on-heap buffers and should always transform them to off-heap buffers. There is also no reason for it to be static, so change that here too.
