Summary

What does the PR accomplish, why was it needed?
This commit adds a new Azure VM ARM64 image with FIPS enabled by default.

Change Log

This image definition is identical to the current marketplace ARM64 image definition, except for the following specific changes:

1. Include the fips-packages.json package list before the initramfs package in the overall package list

2. Set KernelCommandLine.EnableFIPS to true, to inform image generation tools to enable FIPS during image creation

3. Set basename for image as "cblmariner-arm64-gen2-fips"

Does this affect the toolchain?

NO

Test Methodology

• local arm image build and test on Azure
• Check FIPS is enabled by:
  sudo cat /proc/sys/crypto/fips_enabled (returns 1 if enabled)
  sudo sysctl crypto.fips_enabled (returns crypto.fips_enabled = 1 if enabled)
  openssl md5 (# Check if openssl library is running in fips mode)
