Berkus Decker 50b0613f5c Use rust-objcopy tool 
Since cargo-binutils 0.3.1 the `cargo objcopy` causes a build before
copying files, this doesn't work for test-runner.
We only need the actual objcopy tool, not the cargo infra here.

Berkus Decker af1cc83530 Add testing framework 
Based on os.phil-opp.com ideas it includes running test framework in
qemu semihosting mode so that tests can indicate pass or fail to calling
process.

GitHub Actions are configured to run these tests and validate acceptance.

Add test-runner target to perform tests in qemu.

Add -nographic for qemu running tests.

Drop serial for qemu tests as well.
