exec/cpu-common.h: Avoid including unused exec/page-protection.h header

Since commit e74781c0888e ("exec/cpu: Extract page-protection
definitions to page-protection.h") the "exec/cpu-common.h" isn't
using anything defined in "exec/page-protection.h"; remove it.

Include it in few files where it is currently pulled in indirectly,
otherwise we'd get:
