print summary after the build in trace output

[smoors]

examples:

first build failed:

== Summary:
   * [F] Kaleido/0.2.1-GCCcore-13.3.0
   * [-] MultiQC/1.28-foss-2024a

the first build succeeded, the second failed:

== Summary:
   * [S] Kaleido/0.2.1-GCCcore-13.3.0
   * [F] MultiQC/1.28-foss-2024a

both builds succeeded:

== Summary:
   * [S] Kaleido/0.2.1-GCCcore-13.3.0
   * [S] MultiQC/1.28-foss-2024a

Note

with rich, in some cases a summary line like this is printed, showing the installed modules:

0:01:08  1 out of 2 easyconfigs done: Kaleido/0.2.1-GCCcore-13.3.0 (OK)

however, that is not sufficient:

• it is not printed if all builds succeeded
• it is not printed if you don’t have rich installed (or if you specified a different output style)
• it doesn’t show the module that failed and the ones that didn’t build

would be nice to add coloring to the trace output, but we can do that in another PR

@smoors Shouldn't we also include a legend, to indicate what each of the letters mean?

So rather than this:

== Build succeeded for 3 out of 3
== Summary:
   * [S] M4/1.4.19-GCCcore-12.2.0
   * [F] Bison/3.8.2-GCCcore-12.2.0
   * [-] flex/2.6.4-GCCcore-12.2.0

We can print:

== Summary ([-]: skipped, [F]: failed, [S]: success)
   * [S] M4/1.4.19-GCCcore-12.2.0
   * [F] Bison/3.8.2-GCCcore-12.2.0
   * [-] flex/2.6.4-GCCcore-12.2.0
