Andrew Brown e5d25bc216 [doc] Add some documentation for debugging 
The previous documentation only covers how to enable debug info when
embedding Wasmtime. This change should cover the commonly-asked
question: how do I debug in Wasmtime?

Debugging WebAssembly

The following steps describe a common way to debug a WebAssembly module in Wasmtime:

  1. Compile your WebAssembly with debug info enabled, usually -g; for example:

    clang foo.c -g -o foo.wasm

  2. Run Wasmtime with the debug info enabled; this is -g from the CLI and Config::debug_info(true) in an embedding (e.g. see debugging in a Rust embedding)

  3. Use a supported debugger:

    lldb -- wasmtime run -g foo.wasm

    gdb --args wasmtime run -g foo.wasm
