Is this not going to break for the crates which support 32-bit but don't have a tests/wast.rs? I.e. all of them other than wasmtime? But even the wasmtime crate doesn't have that test, only wasmtime-cli does... I guess I am pretty confused around the logic here...

This is abusing the fact that cargo test --workspace --test wast only actually executes tests named wast and everything else is ignored. So this effectively runs cargo test --test wast and nothing else is named wast.
In the long-run I want to get more 32-bit tests running, just needs more support in Pulley for that.

@Kmeakin, happen to know how we can properly get access to these JIT code registration functions so that profiling and debugging and all that with the system tools is a better experience?
This commit extends our CI for i686 and armv7 to test the Pulley backend, namely the full `*.wast` test suite as well as the `wasmtime` crate itself. Note that many `*.wast` tests are still expected to fail at this time. This involved fixing a number of 32-vs-64 bit issues throughout the test suite in various location in this commit.

This PR is based on #9743 and #9744 and those should be reviewed first.
Opening this to get a full run of CI to see what happens on these platforms...
