ArmVirtPkg/ArmVirtXen: don't set PcdTerminalTypeGuidBuffer

According to the

  PCDs not used by modules or in conditional directives

sections of all the build reports for

  {AARCH64,ARM} x {Xen} x {DEBUG,NOOPT,RELEASE} x {feat-0,feat-1}

(12 builds in total), the PCD is not used in any of those builds.

Restrict the setting to the ArmVirtQemu and ArmVirtQemuKernel platforms.
Restrict the TTY_TERMINAL define similarly.

("feat-1" stands for "-D HTTP_BOOT_ENABLE -D NETWORK_IP6_ENABLE -D
SECURE_BOOT_ENABLE -D TTY_TERMINAL", while "feat-0" stands for "".)
