libunwind: add version 1.3-rc1 and variant xz (#8989)

Browse Source 
* libunwind: add version 1.3-rc1 and variant xz

Version 1.3-rc1 is the latest published snapshot from libunwind.

Variant xz adds spack-built support for reading compressed symbol
tables, or else disables this feature.  Without the variant, libunwind
will look for liblzma in /usr/lib.

* Add preferred=True to version 1.2.1 as the last official stable
release.
