[LU-11417] Add llapi_layout_get_by_xattr() interface

Description

The code in llapi_layout_get_by_fd() should be abstracted into a new llapi_layout_get_by_xattr() helper function, which is used by the upper layers and can also be used on a "lov" xattr regardless of how it is obtained. That is useful if the xattr has been fetched from some other method, or a tarball or HSM archive, etc.
