[Patch V3] NetworkPkg: Add PCDs for HTTP DNS RetryCount and RetryInterval

["Heng Luo" <heng.luo@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3889

Currently the HTTP DNS Retry Interval is 2 second and no retry attempt.
If DNS response can't arrive in 2 second, the DNS request is failed,
and then HTTP boot is failed.
In order to resolve this issue, Add PCDs to support RetryCount
and RetryInterval configured in Platform.
