Subject: [PATCH] build: Added a workflow to cross-build targetting AArch64

The result of the workflow can be seen in Checks tab of a PR.
Two targets have been added:
- stable aarch64-unknown-linux-gnu
- stable aarch64-unknown-linux-musl

Note: a temporary step was added before building. We used "sed" command
to remove "with-serde" feature of kvm-bindings in vmm/Cargo.toml.
This step should be removed in future when kvm-bindings is ready.
