Measured on size of e main module (baseline is we don't embed it in application code): * embedding before: +16.5% uncompressed / +9.1% compressed * embedding with this CL: +4% uncompressed / +4.3% compressed When embeddeding deferred load list information into the app (as opposed to a separate json file) we now use a more compact encoding. Specifically: Instead of encoding it as an array of an array of strings (which are module names), we encode it as an array of an array of module ids and construct the module name from the id. To make the array of module ids more compact we utilize the fact that we can sort them and encode in delta encoding (i.e. instead of absolute module ids, encode the diff between previous module id in the list). We put the encoded module id lists in a data section and create `WasmArray<WasmI8>`s from them at startup. When we trigger a load we then decode them into the list of module names. There's more opportunity to optimize it, but it's good to do this as a first step.
