Currently, when running with --trace-turbo, V8 generates a different
.json file for each wasm-to-js thunk that it compiles, but these files
all have the same name "turbo-wasm-to-js-0.json", and only one file is
generated.
This makes it difficult to actually examine the difference in the IR
for this call wrappers produced for different signatures.

This patch fixes this by naming each trace file as:
"wasm-to-js-<kind>-<signature>-0.json", like for example
"turbo-wasm-to-js-5-ii-i-0.json".
