trace-log feature does not take effect after #7626

[feilongjiang]

#7626 changed the cranelift-codegen features from default to host-arch in crates/cranelift/Cargo.toml.

Before this change, I could enable trace by adding trace-log to the features' default list in cranelift/codegen/Cargo.toml.

But now the old way doesn't work, trace-log should be added to crates/cranelift/Cargo.toml like this:

cranelift-codegen = { workspace = true, features = ["host-arch", "trace-log"] }

is that expected behavior?

This is expected behavior in that it's how Cargo features work, but not necessarily expected behavior in that's how things are expected to work. The best solution here would probably be to add a cranelift-trace-log feature to the wasmtime crate and thread that through
