🛡️GPG sign & Verify deb packages

Signing data with a GPG key allows the recipient of the data to check whether any modifications have occurred after the data was signed.

Since release 1.22.0, each Debian package file (.deb file) has been signed with a GPG key, and the signature is included in the archive.

The Public Key has been uploaded to https://keys.openpgp.org/search?q=EA267657A608300C296B8F8AD52C9665A4077678

To verify the signature:

# Download and import the Public Key
curl https://keys.openpgp.org/vks/v1/by-fingerprint/EA267657A608300C296B8F8AD52C9665A4077678 | gpg --import

# Download the driver package
wget https://github.com/intel/linux-npu-driver/releases/download/v1.35.0/linux-npu-driver-v1.35.0.20260722-29947505341-ubuntu2404.tar.gz

[!CAUTION] Due to a firmware issue, the InOrderExecution.RunCopyUsingCmdQueueInOrderMode test occasionally fails on PTL and WCL.

For the -c option of npu-umd-test, the extend.yaml configuration file was used. It can be obtained from the UMD testing documentation and examples provided in the Intel NPU driver repository (umd-testing.md). The tests were run with the following YAML configuration:

# filename: extend.yaml

image_dir: images/

graph_execution:
  - path: add_abc/add_abc.xml
  - path: resnet50.xml
