Engine::detect_precompiled
API to inspect some bytes and determine if they look like a precompiled artifact of either a core wasm module or component. This is something I'll be using soon in an upcoming refactor of the Wasmtime CLI to support components, but it's something we've also talked about before which can be useful for systems storing both precompiled modules and components.Implementation-wise this looks at the ELF header of the input and determines if it's got all the right flags that Wasmtime sets for the various bits and bobs of our object format.
