O-Subject: [RHEL7.6 PATCH BZ 1539280 3/9] memory, exec: Expose all memory block related flags.
Bugzilla: 1539280

From: Junyan He <junyan.he@intel.com>
We need to use these flags in other files rather than just in exec.c,
For example, RAM_SHARED should be used when create a ram block from file.
We expose them the exec/memory.h
