Invokes the given closure with a buffer pointer covering the raw bytes of
the given argument.
The buffer pointer argument to the body closure provides a collection
interface to the raw bytes of arg. The buffer is the size of the
instance passed as arg and does not include any remote storage.
Parameters:arg: An instance to temporarily access through a raw buffer pointer.
body: A closure that takes a raw buffer pointer to the bytes of arg
as its sole argument. If the closure has a return value, it is used as
the return value of the withUnsafeBytes(of:_:) function. The buffer
pointer argument is valid only for the duration of the closure's
execution.
Returns: The return value of the body closure, if any.
