executor: set CpuWeight in cgroup-v2 (#11287) 
Cgroup-v2 uses `cpu.weight` property instead of cpu shares:
https://www.kernel.org/doc/html/latest/admin-guide/cgroup-v2.html#cpu-interface-files
. And it uses a different range (i.e. `[1, 10000]`) from cpu.shares
(i.e. `[2, 262144]`) to make things more interesting.

Luckily, the libcontainer provides a helper function to perform the
conversion
[`ConvertCPUSharesToCgroupV2Value`](https://pkg.go.dev/github.com/opencontainers/runc@v1.0.2/libcontainer/cgroups#ConvertCPUSharesToCgroupV2Value).

I have confirmed that docker/libcontainer performs the conversion as
well in
https://github.com/opencontainers/runc/blob/v1.0.2/libcontainer/specconv/spec_linux.go#L536-L541
, and that CpuShares is ignored by libcontainer in
https://github.com/opencontainers/runc/blob/v1.0.2/libcontainer/cgroups/fs2/cpu.go#L24-L29
.
