We make an undocumented assumption in {CodeSpaceWriteScope} that a
single thread will only work on one module at a time. If this is
violated, the thread-local {code_space_write_nesting_level_} would
prevent the second module from being switched to writable.
This CL adds a second thread local (in debug only) to check that if
there is already a {CodeSpaceWriteScope} open that it contains the same
{NativeModule} as any nested scope.
