MdePkg: Fix overflow issue in BasePeCoffLib
The RelocDir->Size is a UINT32 value, and RelocDir->VirtualAddress is
also a UINT32 value. The current code does not check for overflow when
adding RelocDir->Size to RelocDir->VirtualAddress. This patch adds a
check to ensure that the addition does not overflow.

In case there is no hardware random number generator available,
have the Platform Boot Manager install a pseudo RNG to ensure
the network can be used.
This patch adds the fallback rng (added on ae9be39436)
also to the PlatformBootManagerLibLight, which is used by ArmVirtPkg.

Subject: [PATCH] OvmfPkg: Rerun dispatcher after initializing virtio-rng
RH-Author: Oliver Steffen <osteffen@redhat.com>
RH-MergeRequest: 84: OvmfPkg: Rerun dispatcher after initializing virtio-rng
RH-Jira: RHEL-58631
RH-Acked-by: Gerd Hoffmann <kraxel@redhat.com>
RH-Commit: [1/1] d663321aab28f000c279bfac6dbaaa378678532e (osteffen/edk2)
Since the pixiefail CVE fix the network stack requires a hardware
random number generator. This can currently be a modern CPU supporting
the RDRAND instruction or a virtio-rng device.
The latter is initialized during the BDS phase.
To ensure all depending (network) modules are also started, we need to
run the dispatcher once more after the device was initialized.
Without this, network boot is not available under certain hardware
configurations.
Fixes: 4c4ceb2ceb ("NetworkPkg: SECURITY PATCH CVE-2023-45237")
