kata-types: Introduce QGS port for TD attestation in Hypervisor config

Currently, the TDX Quote Generation Service (QGS) connection in QEMU is
hardcoded to vsock port 4050, which limits flexibility for TD attestation.
While the users will be able to modify the QGS port. To address this
inflexibility, this commit introduces a new qgs_port field within security
info and make it default with 4050.
