Allow architecture specific sched domain NUMA distances that are modified from actual NUMA node distances for the purpose of building NUMA sched domains. Keep actual NUMA distances separately if modified distances are used for building sched domains. Such distances are still needed as NUMA balancing benefits from finding the NUMA nodes that are actually closer to a task numa_group. Consolidate the recording of unique NUMA distances in an array to sched_record_numa_dist() so the function can be reused to record NUMA distances when the NUMA distance metric is changed. No functional change and additional distance array allocated if there're no arch specific NUMA distances being defined.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
