* build and test `wasm32-wasi-preview2` target
This updates `wasi-libc` to include
https://github.com/WebAssembly/wasi-libc/pull/457, which adds preliminary
support for the new `wasm32-wasi-preview2` target.
It also adds support for testing the new target using Wasmtime 16.0.0 and
`wit-component`. Note that Wasmtime produces different output when reporting
errors for Preview 2 components than it does for Preview 1 modules, so I've
added a few .expected files specific to Preview 2.

This patch enables using latest version of wasmtime for testing. This
should also make it possible to running tests for wasm32-wasi-threads
in the future.
* Add a basic testcase for emulated signals.
* Add a testcase for raise(SIGABRT).
* Fix style.
* Actually use all of the C-standard-required signals.
* Update expected stderr.
* Use the right version of this test file.

To support this, add a mechanism for filtering test output to filter
out uninteresting diffs.
This adds some coverage for the code being changed in
https://github.com/WebAssembly/wasi-libc/pull/184.
wasi-libc builds special versions of printf and other routines optimized
for the case where long double and floating-point in general are not
needed. Ensure that everything still compiles and runs.
This adds a very primitive test harness and tests relevant to the recent
changes to how program startup works, as well as the upcoming changes
to support LTO.
