Reorganize release templates.

Reorganize release templates.

Rename "release" config file to "archive" to collect jobs related to
preparing archives for export. "release" jobs are just special cases of
jobs that already fit in other categories.

Move several jobs between the "lint," "documentation," "testing-matrix,"
and "archive" groupings. Sort job definitions within files in terms of
execution dependency, definition dependency, and toolchain version.

In the future, we can probably reduce the distinction between jobs that
are 'release' or not (jobs that always run may choose a code path
according to to $GROMACS_RELEASE) so I'll leave the 'release' jobs
clustered with the non-'release' jobs.
