NetworkPkg/TlsAuthConfigDxe: Provide the UI to support TLS auth configuration

This patch provides the UI to support TLS auth configuration.
* EFI_SIGNATURE_LIST format is used for 'TlsCaCertificate'
variable. So, TLS supports multiple certificate configuration.
* The variable attribute is BS with NV, which only target at
preventing runtime phase attack.
