LibJS/JIT: Update "unwind context" stack in JIT code
Until now, the unwind context stack has not been maintained by jitted code, which meant we were unable to support the `with` statement. This is a first step towards supporting that by making jitted code call out to C++ to update the unwind context stack when entering/leaving unwind contexts. We also introduce a new "Catch" bytecode instruction that moves the current exception into the accumulator. It's always emitted at the start of a "catch" block.
