LibJS: Add set_exception() and change throw_exception() to take a reference

Browse source 
Sometimes we just want to set m_exception to some value we stored
previously, without really "throwing" it again - that's what
set_exception() does now. Since we have clear_exception(), it does take
a reference, i.e. you don't set_exception(nullptr). For consistency I
updated throw_exception() to do the same.
