misc: Update MAINTAINERS with a system tag

The code in system/ currently doesn't have a well-defined tag. Arm
components have traditionally used 'system-arm' and in some cases just
'arm'. This change introduces a separate tag for system software and
related files components.

misc: Add MAINTAINERS file

This file defines all of the commit keywords used for gem5 commits and
the maintainter(s) for each of these keywords.

This patch introduces a number of new keywords, and changes to previous
keywords. The new keywords better follow gem5's directory structure and
are more extensible.

Currently, most keywords do not have a maintainer. More maintainers will
be added as more people volunteer to be maintainers.

This patch also updates the CONTRIBUTING.md file to point to this file
instead of listing the keywords separately. When this file is committed
the wiki will also be updated accordingly.
