Adding LICENSE and test files to crates

Crates are missing LICENSE and test files.
Those files exist only in the git repo.
By adding symbolic links to these files, they are added to the az-???-vtpm crates

How to use

cd az-cvm-vtpm
for i in cvm snp tdx; do
    cargo package --package az-${i}-vtpm;
done

Testing done

for i in cvm snp tdx; do
        tar tf target/package/az-${i}-vtpm-0.7.1.crate | grep -E 'LICENSE|test'
done

Comments

Perhaps it's better to move the test files and change the tests accordingly.
For example: move hcl-report-tdx.bin to az-tdx-vtpm/test
