Fixes for WinRM/PowerShell support in v2.

- Add support for inserting module args into PowerShell modules.  Fixes #11661.
- Support Windows paths containing spaces.  Applies changes from #10727 to v2.  Fixes #9999.  Should also fix ansible/ansible-modules-core#944 and ansible/ansible-modules-core#1007.
- Change how execution policy is set for running remote scripts.  Applies changes from #11092 to v2.  Also fixes ansible/ansible-modules-core#1776.
- Use codepage 65001 (UTF-8) for WinRM connection instead of default (CP437), convert command to UTF-8 and results from UTF-8.  Replaces changes from #10024.  Fixes #11198.
- Close WinRM connection when task completes.
- Use win_stat, win_file and win_copy modules instead of stat, file and copy when called from within other action plugins (only when using WinRM+PowerShell).
- Unquote Windows path arguments before passing to win_stat, win_file, win_copy and slurp modules (only when using WinRM/PowerShell).
- Check for win_ping module to determine if core modules are missing (only when using WinRM/PowerShell).
- Add stdout_lines to result from running low level commands (so stdout_lines is available when using raw/script).
- Update copy action plugin to use shell functions for joining paths and checking for trailing slash.
- Update fetch action plugin to unquote source path when using Windows paths.
- Add win_copy and win_template action plugins that inherit from copy and template.
- Support running .bat and .cmd scripts using default system encoding instead of UTF-8.
- Always send PowerShell commands as base64-encoded blobs to allow for running simple PowerShell commands via raw.
- Support running modules on Windows with interpreters other than PowerShell.
- Update integration tests to support above changes and test unicode fixes.
- Add test for win_user error from ansible/ansible-modules-core#1241 (fixed by ansible/ansible-modules-core#1774).
- Add test for additional win_stat output values (implemented by ansible/ansible-modules-core#1473).
- Add test for OS architecture and name from setup.ps1 (implemented by ansible/ansible-modules-core#1100).

All WinRM integration tests pass for me with these changes.
