This updates the `wasi-libc` submodule to point to `main` and also:
- update tests/testcase.sh to use new wasm32-wasip2 target name
- update various tests/**/*.expected files to match Wasmtime output

Currently the `bin` directory installed by wasi-sdk is not currently
suitable for putting in `$PATH` in all cases because it can shadow a
system-installed `clang` executable which is intended for native
binaries. For Linux distributions with gcc-based cross-compilers I've
often seen the pattern where they're installed as `$target-gcc` and so
I've taken a leaf out of their books to do that here as well.
This commit adds, currently alongside the preexisting `clang`
executable, target-prefixed executables such as `wasm32-wasi-clang` and
`wasm32-wasi-clang++`. These executables are symlinks to the `clang`
executable itself in the same manner that `clang++` is a symlink to
`clang` itself.
I'll also note that this doesn't fix the problem of "add the wasi-sdk
bin dir to PATH" because `clang` and other prominent executables are
still there. My hope though is that this opens up a future refactoring
for doing so.
* Start renaming preview1 to p1 and preview2 to p2
This commit is a reflection of WebAssembly/wasi-libc#478 into this
repository where a few changes are happening:
* A new `wasm32-wasip1` sysroot is prepared matching `wasm32-wasi`
* A new `wasm32-wasip1-threads` sysroot is prepared matching `wasm32-wasi-threads`
* The `wasm32-wasi-preview2` target is renamed `wasm32-wasip2`
I've done a bit of makefile refactoring to deduplicate things a bit now
that there's a number of targets being built.
The long-term goal would be to remove the `wasm32-wasi` and
`wasm32-wasip1-threads` targets, but that's not proposed just yet at
this time.
* Use $(CLANG_VERSION) instead of hardcoding
* 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.

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.
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.
