Make ASCII PC/KSP/SNES/TSView() code and output in a standard style

The code that prints the ASCII view for solvers was occasionally inconsistent:
1) TSView printed the type specific information after the general info while
all other solvers printed it before (right after the name of the type is printed)
2) KSPView consistently printed the name of the subtype on EACH line of the subtypes
output as did a few of the PC and SNES viewers. Since they are all printed indented
directly below the subtype name there is no reason to print this information on each line
3) TSView printed output about number of linear solvers and SNES even for explicit
methods, which is goofy.
4) a few other minor formatting and consistency issues where fix.

Merge branch 'tisaac/feature-plex-tests-new'

This merge changes PetscSpace and PetscQuadrature to have a number of
components, so that vector-valued functionals can be defined for
non-Lagrange finite elements. Along the way, this branch also converts
the regression tests related to DMPlex that were in config/builder.py to
the new test harness, and makes lots of changes necessary for them to
be portable tests.

Merge branch 'tisaac/feature-fe-dual-apply' into tisaac/feature-plex-tests-new

There has unfortunately been a lot of interplay between our work to
change the petscspace/dualspace to accept vector components, and the
work to transfer the tests in config/builder.py to the new test harness.

so that I only have one feature branch to handler when merging into
