[SRU][N:linux-nvidia-6.14][PATCH] UBUNTU: [Config] enable MEMCG_V1 and CPUSETS_V1 on Noble 6.14+

BugLink: https://bugs.launchpad.net/bugs/2122368

Re-enable cgroup v1 support for Noble 6.14+. Starting in 6.12, cgroup v1
support was placed behind CONFIG_CPUSETS_V1 and CONFIG_MEMCG_V1 which
defaults to n.

There is still plently of workloads that require v1 support. The 6.8
kernel still supports v1. Re-enable v1 support on linux-nvidia-6.14 too.

Set CONFIG_CPUSETS_V1 and CONFIG_MEMCG_V1 to y.
