Public bug reported:

upgrade amd64-microcode with new microcode & better initramfs hook

[Impact]

 * New microcode is available

 * It is hard to generate initrd, with all microcodes included because the initramfs hook ignores 
   preset defaults. Adjust hook to take preset defaults into account.

[Test Case]

 * There is no testcase for new microcode, as it is unknown what has
changed.

 * Install new package, and check that initrd with default settings (i.e. modules=most) has amd64 
   microcode included. And that with modules=dep|list it only does so, if one is on AMD cpu.

 * Install initramfs-tools-ubuntu-core from snap image PPA, the resulting initrd should contian 
   both amd64 and intel microcode, despite using modules=list, due to the conf.d default settings
   it overrides.

[Regression Potential]

 * New microcode is published without a changelog, thus it is unknown what it fixes or regresses, 
   yet it is recommeded to upgrade it. The 17h family microcode has been updated, almost doubling in size.

 * The hook default behaviour is not changed, only integration with
custom conf.d's is improved.

 * This both shows the SRU team that the risks have been considered,
   and provides guidance to testers in regression-testing the SRU.
