Use SwiftWasm 5.5.0, bump version to 0.12.0 (#266)

`async-http-client` package is now pinned to 1.6.4, as 1.7.0 and later versions caused issues with toolchain downloads (see swift-server/async-http-client#488 for more details).

I've also updated toolchain downloader code to bubble up download errors, which previously were hidden and made it very hard to diagnose these issues.

* Use SwiftWasm 5.5.0, bump version to 0.12.0

* Pin AHC to 1.8.0

* Pin AHC to 1.6.4, always remove downloaded archives

* Fix `defer` build issue
