* Improve handling of strings for backtraces Largely avoid storing strings at all in the `wasmtime-*` internal crates, and instead only store strings in a separate global cache specific to the `wasmtime` crate itself. This global cache is inserted and removed from dynamically as modules are created and deallocated, and the global cache is consulted whenever a `Trap` is created to symbolicate any wasm frames. This also avoids the need to thread `module_name` through the jit crates and back, and additionally removes the need for `ModuleSyncString`. * Run rustfmt
