Load generated trampolines into jitdump when profiling (#3344)

* Load generated trampolines into jitdump when profiling

This commit updates the jitdump profiler to generate JIT profiling
records for generated trampolines in a wasm module in addition to the
functions already in a module. It's also updated to learn about
trampolines generated via `Func::new` and friends. These trampolines
were all not previously registered meaning that stack traces with these
pc values would be confusing to see in the profile output. While the
names aren't the best it should at least be more clear than before if a
function is hot!

* Fix more builds
