apiserver: accept large identity header sets with Go 1.27

Go 1.27 rejects requests with more than 500 header values by default
(http.Server.MaxHeaderValueCount, golang/go#79936). kube-apiserver
forwards each of a user's groups to aggregated API servers as a
separate X-Remote-Group header, so users with about 500 groups would
receive HTTP 431 from cdi-apiserver once it is built with Go 1.27.

Set MaxHeaderValueCount to 16384 on the CDI API server for Go 1.27+
builds, matching kube-apiserver: 1 MiB MaxHeaderBytes at about 64 bytes
per value. Earlier toolchains use a no-op.
