[BinFmt] Identify and notify internal partners relying on custom BuildEventArgs

[JanKrivanek]

Background

#6215
This subitem is focused on mitigating internal impact of #8823

Prerequisities

• Deprecate binfmt in build event args #8917
• [BinFmt] Facilitate proper documentation of Custom BuildEventArgs deprecation and replacement #9016
• [BinFmt] Opt-in warn on Custom BuildEventArgs usage #9008

Expected output

• List of MSFT repositories/codefiles (GH, AzDO) that employ deriving from BuildEventArgs or any of its subclasses (ideally even including those outside of the MSBuild repo identified during this discovery - in case a custom hierarchy would span across multiple teams)
• Owners for those files
• Information email about the refactoring and recommended approach sent out
• (Optional, but very helpful) - perform the search as well accross the public comunity code

I have searched internal AzDO orgs and GitHub orgs for usages of derived *EventArgs. Majority of found occurrences was limited to full framework.

I recommend to communicate these to partners:

1. CPS does compile into net7 for green extension purposes. We can expect they will migrate to net8+ in future. I have found occurrence there

2. VS related things are currently compiled only into framework, however, we can expect it will eventually migrate to dotnet. To easy such future migration, we should consider to migrate away from derived custom events to using general custom event. I have found several places in VS repo. For example here, here, and here. I don't know if these are still valid part of VS. If we agree on preventive migrate in VS repo, more extensive search shall be conducted.

Above communication might take place after we merge non-breaking changes in MSBuild main so partners can action on it. After partners ACK migration finished, we will proceed with breaking-changes.

@baronfel, @rainersigwald Do you agree with these course of actions?
