Removes struct load_seg, the mobj stored in struct load_seg is already
stored in struct vm_region. A flag VM_FLAG_EXCLUSIVE_MOBJ is added to
indicate that the mobj in struct vm_region should be freed instead of
just ignored when removing a region.

core: store file pointer in struct mobj_with_fobj

Stores the file pointer in struct mobj_with_fobj instead of in struct
load_seg. When the mobj is freed the stored file pointer has its
reference counter decreased instead of relying on free_seg() to do it
when the struct load_seg is freed.

core: split TEE_MATTR_* defines

Splits the TEE_MATTR_* defines into two groups, TEE_MATTR_* and VM_FLAG_*.
TEE_MATTR_* is restored to only handle mappings attributes and permissions.
The new group VM_FLAG_* is added to tag regions with purpose and such.

As a consequence user_ta_map(), vm_map_pad() and vm_map() takes one more
argument, the flags field.

struct vm_region also gains a flags field, but since only the lower bits
are used in the flags and attr fields they are each stored as uint16_t
instead.
