Update to v6.12 kernel headers.

Kernel headers coming from:

Git: https://android.googlesource.com/kernel/common/
Branch: android-mainline
Tag: android-mainline-6.12

Comment out the TAG usage of the __struct_group macro in linux/pkt_cls.h.
The kernel upstream is either going to revert this usage of __struct_group
or fix this in another way. When set, it creates a named struct in an
anonyous union, which is not allowed in C++.

Test: Builds and bionic unit tests pass on raven.
