The jump table sizes were added to the estimated code size, and then
again added for computing the reservation size for the code. This CL
moves the jump table size from {EstimateNativeModuleCodeSize} to
{EstimateNativeModuleMetaDataSize} so it is still considered for the
total memory associated with the {NativeModule}, but only added once for
the code space reservation.
