Revert "Reland "[runtime] Move Context::native_context to the map""
This reverts commit c7c47c68f2c0eb1155cfacab785aba54f61d9218.
Reason for revert: breaks TSAN

> frame is properly set up. In the case we looked at, the profiler took a
> sample right before writing the frame marker indicating a builtin frame,
> causing the "context" pointer from that frame to be a bytecode array. Since
> we'll read random garbage on the stack as a possible context pointer, I made
> the code reading the native context from it a little more defensive.
