[Bug]: Don't Use Memory Attribute Protocol in Core and Optimize SetMemoryAttributes

[os-d]

Is there an existing issue for this?

• [X] I have searched existing issues

Current Behavior

There is an instance of GetMemoryAttributes in DxeCore to avoid calling SetMemoryAttributes if no attributes are different. The memory attribute protocol should only be used by bootloaders or other non-core components. To not lose the performance gain, add smarts to SetMemoryAttribute to only go down the set path if the attributes are not the same.
