Philip Pfaffe 8ca19603a2 [wasm debug] Cache name tables for the wasm debug proxy. 
Also construct the `JSMap`s used to store these names lazily and
only on-demand, and construct them directly instead of first doing
a `std::vector<Handle<String>>` and using that to construct the
`JSMap`. The latter resulted in a gigantic root set of 150k+ handles,
which wasn't well received by the GC.
