* Enable jitdump profiling support by default This the result of some of the investigation I was doing for #1017. I've done a number of refactorings here which culminated in a number of changes that all amount to what I think should result in jitdump support being enabled by default: * Pass in a list of finished functions instead of just a range to ensure that we're emitting jit dump data for a specific module rather than a whole `CodeMemory` which may have other modules. * Define `ProfilingStrategy` in the `wasmtime` crate to have everything locally-defined * Add support to the C API to enable profiling * Documentation added for profiling with jitdump to the book * Split out supported/unsupported files in `jitdump.rs` to avoid having lots of `#[cfg]`. * Make dependencies optional that are only used for `jitdump`. * Move initialization up-front to `JitDumpAgent::new()` instead of deferring it to the first module. * Pass around `Arc<dyn ProfilingAgent>` instead of `Option<Arc<Mutex<Box<dyn ProfilingAgent>>>>` The `jitdump` Cargo feature is now enabled by default which means that our published binaries, C API artifacts, and crates will support profiling at runtime by default. The support I don't think is fully fleshed out and working but I think it's probably in a good enough spot we can get users playing around with it!
