Update generic-x86-64 Linux kernel to 6.12 (#3767)

* Linux: Update kernel to 6.12.6

* Linux 6.12

* #3767 (comment)

* #3767 (comment)

* Add patch descriptions, kernel ver conditionals

Signed-off-by: Nick Venenga <nick@venenga.com>

* Remove extra zram compression algos

* Undo fragment files config change

...for platforms that didn't receive kernel updates

* Sort Dockerfile apt packages

* Add Upstream refs to patches

* Re-enable TC

* Restore v6.6.y kernel fragments

* Update buildroot to rebased branch

* Apply 6.12 migration only to generic-x86-64

* package/eq3_char_loop: port patch from RaspberryMatic by @jens-maus

* package/generic_raw_uart: port patch from RaspberryMatic by @jens-maus

* Restore buildroot-external/board/pc/patches/linux

It's used in ova and generic-aarch64 defconfigs. Keep the path removed from
generic-x86-64 defconfig.

* Split linux patches to be version-specific

The IPv6 reachability patch needs different context on 6.6.y and 6.12.y -
introduce version-specific linux directories. To avoid the need for extra
directory for version used in RPi, copy those patches to its patches directory.

* Replace removed Intel Skylake audio driver with Intel AVS

The Skylake driver was removed and should be now replaced either by Intel HD
Audio or Intel AVS. Remove the old options and enable AVS.
