Add rustup target add wasm32v1-none step to:
- tests-misc.yml: test-pezframe-examples-compile-to-wasm, cargo-check-benches, check-metadata-hash, cargo-check-each-crate
- tests-linux-stable.yml: test-linux-stable-int, test-linux-stable-runtime-benchmarks, test-linux-stable, test-linux-stable-no-try-runtime
- build-misc.yml: build-runtimes-polkavm
This fixes WASM build failures in container jobs where the wasm32v1-none target is not available by default.
