exewrapper: avoid directly linking against python3X.dll

Subsequent code calls `LoadLibrary()` to attempt to load the DLL, but because of
this symbol reference, there is an attempt to load the DLL used during the build
prior to `_main()` running.  This causes the whole process to fail if the DLL
isn't in the standard search path.  That also means it will never load the DLL
for HackableMercurial.  (Maybe we should get rid of that for py3, since you can
install python for a user without admin rights?)

This could also be resolved by calling `GetProcAddress()` on the symbol and
dereferencing it, but using the environment variable is consistent with the
*.bat file since fc8a5c9ecee0.  (The environment variable persists after the
interpreter is initialized.)

Far more concerning is somehow I've gotten my system into a state where setting
the flag causes any output to the pager to be lost (as if it wasn't set at all)
in MSYS, cmd.exe, WSL, and PowerShell using py3.9.0, but the environment
variable works properly.  I'm sure this flag worked on some versions of py3, so
I'm not sure what's going on here.  This is might be related to init config
related changes in 3.8[1], since it works with 3.7.8, but fails with 3.8.1.
Somebody who understands encoding issues better than I do should give some
thought to if we need to make some changes to our encoding strategy on Windows
with py3.

With or without the flag/envvar, there is proper output if the command is
directly paged by piping to `more.com` (in any environment) or `less` (in MSYS
and WSL), or if paging is disabled with `--pager=no`.  Legacy mode is required
though when Mercurial decides to spin up a pager.

Test rebase with obsolete
==========================

Enable obsolete

  $ cat >> $HGRCPATH << EOF
  > [command-templates]
  > log= {rev}:{node|short} {desc|firstline}{if(obsolete,' ({obsfate})')}
  > [experimental]
  > evolution.createmarkers=True
  > evolution.allowunstable=True
  > [phases]
  > publish=False
  > [extensions]
  > rebase=
  > drawdag=$TESTDIR/drawdag.py
  > strip=
  > EOF

Test that bookmark is moved and working dir is updated when all changesets have
equivalents in destination
  $ hg init rbsrepo && cd rbsrepo
  $ echo "[experimental]" > .hg/hgrc
  $ echo "evolution=true" >> .hg/hgrc
  $ echo root > root && hg ci -Am root
  adding root
  $ echo a > a && hg ci -Am a
  adding a
  $ hg up 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo b > b && hg ci -Am b
  adding b
  created new head
  $ hg rebase -r 2 -d 1
  rebasing 2:1e9a3c00cbe9 tip "b"
  $ hg log -r .  # working dir is at rev 3 (successor of 2)
  3:be1832deae9a b (no-eol)
  $ hg book -r 2 mybook --hidden  # rev 2 has a bookmark on it now
  bookmarking hidden changeset 1e9a3c00cbe9
  (hidden revision '1e9a3c00cbe9' was rewritten as: be1832deae9a)
  $ hg up 2 && hg log -r .  # working dir is at rev 2 again
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  2:1e9a3c00cbe9 b (rewritten using rebase as 3:be1832deae9a) (no-eol)
  $ hg rebase -r 2 -d 3 --config experimental.evolution.track-operation=1
  note: not rebasing 2:1e9a3c00cbe9 mybook "b", already in destination as 3:be1832deae9a tip "b"
Check that working directory and bookmark was updated to rev 3 although rev 2
was skipped
  $ hg log -r .

  $ hg bookmarks

Obsoleted working parent and bookmark could be moved if an ancestor of working
parent gets moved:

  $ hg update D1 -q
  $ hg bookmark book -i
  $ hg rebase -r B+D1 -d E
  rebasing 1:112478962961 B "B"
  note: not rebasing 5:15ecf15e0114 book D1 tip "D1", already in destination as 2:0807738e0be9 D2 "D2"
