Pierre Langlois 2970249a72 [mjsunit] Do not generate compiler traces for the entire snapshot.
The `compiler-trace-flags.js` test just makes sure the various --trace-turbo*
flags do not cause V8 to crash. However, on builds with no snapshot, they would
generate a *lot* of output as they were tracing the compiler while generating
the snapshot.

Let's set the `--trace-turbo-filter` flag to make sure we only trace the test
functions. Sadly, WASM functions do not have a name, just an index, so we have
to split this test into two.
