EmbeddedPkg: Mark DMA Memory Allocations XP By Default
When allocating memory for a non-coherent DMA device, the current core
code removes the XP attribute, allowing code to execute from that
region. This is a security vulnerability and unneeded. This change
updates to mark the region as XP when allocating memory for the
non-coherent DMA device.
