Topic: wasmtime / PR #5341 Add a `WasmBacktrace::new()` constructor

alexcrichton opened PR #5341 from manual-backtrace to main:

This commit adds a method of manually capturing a backtrace of WebAssembly frames within a Store. The new constructor can be called with any AsContext values, primarily &Store and &Caller, during host functions to inspect the calling state.

For now this does not respect the Config::wasm_backtrace option and instead unconditionally captures the backtrace. It's hoped that this can continue to adapt to needs of embedders by making it more configurable int he future if necessary.

Closes #5339

Having two constructors, one forcing and one respecting the config, might be nice.

Maybe also mention that this will only contain Wasm frames from within the given store, not other stores' frames that might be on the stack.
