Deprecate Python win32_event_log check implementation

[clarkb7]

What does this PR do?

Deprecate the Python win32_event_log implementation, add legacy_mode_v2 option to enable using it if necessary.

See DataDog/datadog-agent#20701 for the new check implementation

Motivation

Part of effort to consolidate the event log collection implementations.

https://datadoghq.atlassian.net/browse/WINA-519

Additional Notes

The Python WMI implementation (legacy_mode: true) is still the default for backwards compatibility purposes. Thus legacy_mode: false must still be set (see #15907).

WMI implementation:

• no options set, or legacy_mode: true explicitly set

Python Event Log implementation

• legacy_mode_v2: true explicitly set (it is not necessary to also explicitly set legacy_mode: false)

Go Event Log implementation

• legacy_mode: false explicitly set

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• Changelog entries must be created for modifications to shipped code
• Add the qa/skip-qa label if the PR doesn't need to be tested during QA.
