Introduce a driver that allows users to disable the EFI Memory Attribute
protocol through an HII setup option, in order to work around a broken
version of rhboot's shim used in some distros (e.g. CentOS Stream 9)
which incorrectly invokes the protocol and results in a Synchronous
Exception.
Default is enabled, which can also be overridden at build time by
changing `gEmbeddedTokenSpaceGuid.PcdMemoryAttributeEnabledDefault`.
It is only applicable to ARM64 and there isn't any other technical
reason for disabling this security feature.
