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. See: - https://github.com/microsoft/mu_silicon_arm_tiano/issues/124 - https://edk2.groups.io/g/devel/topic/99631663 - https://github.com/tianocore/edk2/pull/5840 Signed-off-by: Mario Bălănică <mariobalanica02@gmail.com>

"Some old OS loader versions (e.g. as found in CentOS Stream 9) do not properly support the protocol and may cause a Synchronous Exception. This security feature can be disabled to work around the issue; otherwise it should be kept enabled."
