Pat Hickey 22433ed726 wiggle: new error configuration for generating a "trappable error" (#5276) 
* Add a new "trappable" mode for wiggle to make an error type

start refactoring how errors are generated and configured

put a pin in this - you can now configure a generated error

but i need to go fix Names

Names is no longer a struct, rt is hardcoded to wiggle

rest of fixes to pass tests

its called a trappable error now

don't generate UserErrorConversion trait if empty

mention in macro docs

* undo omitting the user error conversion trait when empty

wiggle

Wiggle is a code generator for the host side of a witx interface. It is invoked as a Rust procedural macro.

Wiggle is not specialized to any particular WebAssembly runtime. It is usable in at least Wasmtime and Lucet.

Learning more

Read the docs on docs.rs.

There are child crates for integrating with Wasmtime and Lucet.

The wasi-common crate is implemented using Wiggle and the wasmtime-wasi crate integrates wasi-common with the Wasmtime engine.

Andrew Brown wrote a great blog post on using Wiggle with Wasmtime.
