e1000e: Add support for Tiger Lake and Alder Lake Devices

BugLink: https://bugs.launchpad.net/bugs/2023955

[Impact]

Due to fips for jammy not being available yet, users with requirements to be fips certified or fips compliant have to use focal, and many are finding certain hardware devices do not work on their brand new laptops.

I know of several users who use the following laptops who are missing Ethernet NIC support. In Sustaining Engineering we started a spreadsheet to track them all, and their hardware.

Laptops:
Dell Precision 7670
Dell Precision 5560
Dell Latitude 7230 Rugged Extreme

Ideally we try and get the Ethernet NIC working by enabling PCI IDs for the Intel e1000e driver, so users can run focal until jammy-fips is available.

[Testcase]

Use a laptop with a Intel Tiger Lake or Intel Alder Lake architecture, for example:

Dell Precision 7670
Dell Precision 5560
Dell Latitude 7230 Rugged Extreme

Start the machine up and see if Ethernet comes up and functions.

There is a test kernel available in the following ppa:

https://launchpad.net/~mruffell/+archive/ubuntu/lp2023955-test

If you install the test kernel and reboot, ethernet should work properly.

[Where Problems could occur]

We are enabling hardware support on an older kernel by enabling PCI IDs. There will be users out there with currently broken hardware, and by enabling the NIC to function, will find that their ethernet will suddenly start working. This might be bad if they use wifi or usb ethernet and are not expecting network changes. Users can solve this by unplugging the ethernet cable.

There is also a chance that in some hardware combinations, there might be missing driver support, which causes ethernet to misbehave.

If a regression were to occur, users would need to use the ip command to disable their interfaces while a fix is investigated.
