[Hector CAO]

@mkukri and @juliank

Thanks so much for the feedback and work
Now, i would like to ask if we can consider to SRU it to 24.04 because we are having CC story for 24.04 with our Kobuk project

Title:
  Missing measurements on confidential computing platforms (Intel TDX)

Status in grub:
  Unknown
Status in The Kobuk project:
  Confirmed
Status in grub2-signed package in Ubuntu:
  New
Status in grub2-unsigned package in Ubuntu:
  Confirmed

Bug description:
  When we run a Confidential VM with grub bootlodaer on Intel TDX
  platform, the module tpm is not loaded and boot measurements are not
  done for the guest VM.

  This bug will prevent grub of doing measurements on confidential computing platform
  (the bug has been confirmed on Intel TDX). This lack of measurements will break the
  remote attestation
