MSVC build system installs extra executables

I don't know if this has been discussed before, but I mentioned recently
(<https://www.postgresql.org/message-id/e4233934-98a6-6f76-46a0-992c0f4f1208%40dunslane.net>)
that I think the MSVC build system is too eager about installing
executables it builds. In particular, it installs these binaries for
which the analogs are not installed by the makefile system:

isolationtester.exe

libpq_pipeline.exe

pg_isolation_regress.exe

pg_regress_ecpg.exe

pg_regress.exe

zic.exe

Do we want to do anything about that? ISTM we should be installing
identical sets of binaries as far as possible. The installation of
libpq_pipeline.exe is apparently what has led Justin Pryzby to think
it's OK to undo the effect of commit f4ce6c4d3a on vcregress.pl.
