The [wasmtime v37 release](https://github.com/bytecodealliance/wasmtime/releases/tag/v37.0.0) "now fully implements the WebAssembly exception-handling proposal." Support for exception-handling is disabled by default, but will be made default in the future (according to the release notes). To use this new wasmtime feature, we do two things at a high level: 1. Update wasmtime dependency to version 37 2. Add a "wasmtime-exceptions" Extism feature, disabled by default. Updating to the new wasmtime dependency required some semantical changes to how the cache is configured. There is also a new `ExternType` to match on when handling invalid imports. My use case for this feature is being able to execute Lua code from Extism. In actuality, I'm running a Rust plugin, which is using [mlua](https://github.com/mlua-rs/mlua) to execute the Lua. I have it working locally with this change. Fwiw, mlua recently added [support to compile to wasi](https://github.com/mlua-rs/mlua/issues/366), which should make this all work end-to-end with no special patches if we can get this merged. This is my first time working on the Extism codebase, so please let me know if I missed anything.
