Remove reset of testtablespace from pg_regress on Windows

testtablespace is an extra path used as tablespace location in the main
regression test suite, computed from --outputdir as defined by the
caller of pg_regress (current directory if undefined).

This special handling was introduced as of f10589e to be specific to
MSVC, as we let pg_regress' Makefile handle this cleanup in other
environments. This moves the cleanup to the MSVC script running
regression tests instead where needed: check, installcheck and
upgradecheck. I have also checked this patch on MSVC with repeated runs
of each target.

This patch has carefully removed the ability to run the regression tests
as a Windows administrative user, as I just discovered. This was the
whole point of commit ce5d3424d6.

I assume the testing referred to above was not as a privileged user. I
think this should be reverted.

cheers

Thanks Andrew. This was discussed on the original thread and what I
wanted to do a rvert if you look at its newest history:
/messages/by-id/20200623014036.GF50978@paquier.xyz
And then, the thread just stalled.. So I was not sure if something
was actually wanted or not.

Now, I don't think that just a simple revert is the best answer we can
provide. Just look at this comment in pg_regress.c that does not give
a hint that we actually should not remove this code:
- * On Windows only, clean out the test tablespace dir, or create it if it
- * doesn't exist. On other platforms we expect the Makefile to take care
- * of that. (We don't migrate that functionality in here because it'd be
- * harder to cope with platform-specific issues such as SELinux.)
- *
- * XXX it would be better if pg_regress.c had nothing at all to do with
- * testtablespace, and this were handled by a .BAT file or similar on
- * Windows. See pgsql-hackers discussion of 2008-01-18.

So instead I would like to propose the attached, reworking this
comment as follows (basically a revert, except for this comment):
+   /*
+    * On Windows only, clean out the test tablespace dir, or create it if it
+    * doesn't exist so as it is possible to run the regression tests as a
+    * Windows administrative user account with the restricted token obtained
+    * when starting pg_regress.  On other platforms we expect the Makefile
+    * to take care of that.
+    */

What do you think?

I certainly agree we should document more clearly why it's there, to
help forestall anyone else who comes along and thinks it would just be
neater to remove it. so +1.

cheers
