Update wasmtime latest to 43.x requires error type updates

[jsturtevant]

Wasmtime 42.0.0 introduced a breaking change (bytecodealliance/wasmtime#12309) that replaces anyhow::Error with a built-in wasmtime::Error type across all public APIs. This blocks upgrading from 41.x.

Currently hyperlight-wasm-runtime uses ? to propagate wasmtime errors into HyperlightGuestError, which implements Fromanyhow::Error but not Fromwasmtime::Error.
