Ard Biesheuvel a2ed40c02b MdeModulePkg/DxeCore: base code protection on permission attributes
Instead of assuming that a PE/COFF section of type EFI_IMAGE_SCN_CNT_CODE
can always be mapped read-only, classify a section as a code section only
if it has the executable attribute set and the writable attribute cleared.

This adheres more closely to the PE/COFF spec, and avoids issues with
Linux OS loaders that may consist of a single read/write/execute section.
