automation: delete code related to Python 2.7 support

The building of Inno and WiX installers took a python_version argument
that allowed us to specify "2" or "3" for the major Python version. Since
we no longer support Python 2, we can delete this argument and everything
feeding into it.

#require sqlite no-chg

The sqlitestore backend leaves transactions around when used with chg.
Since this backend is primarily intended as proof-of-concept for
alternative storage backends, disable it for chg test runs to avoid
the instability.

New repo should not use SQLite by default

  $ hg init empty-no-sqlite
  $ hg debugrequires -R empty-no-sqlite
  dotencode
  dirstate-v2 (dirstate-v2 !)
  fncache
  generaldelta
  persistent-nodemap (rust !)
  revlog-compression-zstd (zstd !)
  revlogv1
  share-safe
  sparserevlog
  store

storage.new-repo-backend=sqlite is recognized

  $ hg --config storage.new-repo-backend=sqlite init empty-sqlite
  $ hg debugrequires -R empty-sqlite
  dotencode
  dirstate-v2 (dirstate-v2 !)
  exp-sqlite-001
  exp-sqlite-comp-001=zstd (zstd !)
  exp-sqlite-comp-001=$BUNDLE2_COMPRESSIONS$ (no-zstd !)
  fncache
  generaldelta
  persistent-nodemap (rust !)
  revlog-compression-zstd (zstd !)
  revlogv1
  share-safe
  sparserevlog
  store

  $ cat >> $HGRCPATH << EOF

Can force compression to zlib

  $ hg --config storage.sqlite.compression=zlib init empty-zlib
  $ hg debugrequires -R empty-zlib
  dotencode
  dirstate-v2 (dirstate-v2 !)
  exp-sqlite-001
  exp-sqlite-comp-001=$BUNDLE2_COMPRESSIONS$
  fncache
  generaldelta
  persistent-nodemap (rust !)
  revlog-compression-zstd (zstd !)
  revlogv1
  share-safe
  sparserevlog
  store

Can force compression to none

  $ hg --config storage.sqlite.compression=none init empty-none
  $ hg debugrequires -R empty-none
  dotencode
  dirstate-v2 (dirstate-v2 !)
  exp-sqlite-001
  exp-sqlite-comp-001=none
  fncache
  generaldelta
  persistent-nodemap (rust !)
  revlog-compression-zstd (zstd !)
  revlogv1
  share-safe
  sparserevlog
  store

Can make a local commit

  $ hg init local-commit
  $ cd local-commit
  $ echo 0 > foo
  $ hg commit -A -m initial
  adding foo

That results in a row being inserted into various tables

  $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF
  > SELECT * FROM filepath;
  > EOF
  1|foo

  $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF
  > SELECT * FROM fileindex;
  > EOF
  1|1|0|-1|-1|0|0|1||6/\xef(L\xe2\xca\x02\xae\xcc\x8d\xe6\xd5\xe8\xa1\xc3\xaf\x05V\xfe (esc)

  $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF
  > SELECT * FROM delta;
  > EOF
  1|1|	\xd2\xaf\x8d\xd2"\x01\xdd\x8dH\xe5\xdc\xfc\xae\xd2\x81\xff\x94"\xc7|0 (esc)
  

Tracking multiple files works

  $ echo 1 > bar
  $ hg commit -A -m 'add bar'
  adding bar

  $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF
  > SELECT * FROM filedata ORDER BY id ASC;
  > EOF
  1|1|foo|0|6/\xef(L\xe2\xca\x02\xae\xcc\x8d\xe6\xd5\xe8\xa1\xc3\xaf\x05V\xfe|-1|-1|0|0|1| (esc)
  2|2|bar|0|\xb8\xe0/d3s\x80!\xa0e\xf9Au\xc7\xcd#\xdb_\x05\xbe|-1|-1|1|0|2| (esc)

Multiple revisions of a file works

  $ echo a >> foo
  $ hg commit -m 'modify foo'

  $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF
  > SELECT * FROM filedata ORDER BY id ASC;
  > EOF
  1|1|foo|0|6/\xef(L\xe2\xca\x02\xae\xcc\x8d\xe6\xd5\xe8\xa1\xc3\xaf\x05V\xfe|-1|-1|0|0|1| (esc)
  2|2|bar|0|\xb8\xe0/d3s\x80!\xa0e\xf9Au\xc7\xcd#\xdb_\x05\xbe|-1|-1|1|0|2| (esc)
  3|1|foo|1|\xdd\xb3V\xcd\xde1p@\xf7\x8e\x90\xb8*\x8b,\xe9\x0e\xd6j+|0|-1|2|0|3|1 (esc)
