[Bug 1864965] [NEW] Add Intel RAID/RST detection with NVMe devices

[Launchpad Bug Tracker]

[Impact]

The disk-detect.sh supports to detect if Intel RAID/RST mode is
activated as NVMe devices are remapped to PCI bus. Based on this,
ubiquity installer can take advantage of detection and handle such a
case with improved user experience.

[Test Case]

There are several ways to test this case, but one of them will be
integration test:

In ubiquity, hw-detect will be sourced, and then import disk-detect.sh to call remapped_nvme_probe(). Then use the following command to get debconf value:
$ echo "get disk-detect/activate_remapped_nvme" | sudo debconf-communicate
0 True

[Regression Potential]

Some case will be different, especially the system doesn't have AHCI
when RAID mode was set in BIOS, so that PCI attribute "remapped_nvme" is
gone.

[Other Info]

To upstream to debian sid is another WIP item.
