Integrate Lightbeam with latest Wasmtime master (#1232)

Browse Source 
* Implement trap info in Lightbeam

* Start using wasm-reader instead of wasmparser for parsing operators

* Update to use wasm-reader, some reductions in allocation, support source location tracking for traps, start to support multi-value

The only thing that still needs to be supported for multi-value is stack returns, but we need to make it compatible with Cranelift.

* Error when running out of registers (although we'd hope it should be impossible) instead of panicking

* WIP: Update Lightbeam to work with latest Wasmtime

* WIP: Update Lightbeam to use current wasmtime

* WIP: Migrate to new system for builtin functions

* WIP: Update Lightbeam to work with latest Wasmtime

* Remove multi_mut

* Format

* Fix some bugs around arguments, add debuginfo offset tracking

* Complete integration with new Wasmtime

* Remove commented code

* Fix formatting

* Fix warnings, remove unused dependencies

* Fix `iter` if there are too many elements, fix compilation for latest wasmtime

* Fix float arguments on stack

* Remove wasm-reader and trap info work

* Allocate stack space _before_ passing arguments, fail if we can't zero a xmm reg

* Fix stack argument offset calculation

* Fix stack arguments in Lightbeam

* Re-add WASI because it somehow got removed during rebase

* Workaround for apparent `type_alias_impl_trait`-related bug in rustdoc

* Fix breakages caused by rebase, remove module offset info as it is unrelated to wasmtime integration PR and was broken by rebase

* Add TODO comment explaining `lightbeam::ModuleContext` trait
