Auto merge of #85097 - Mark-Simulacrum:stable-next, r=Mark-Simulacrum 1.52.1
[stable] 1.52.1 release Note that this may not be the version we end up going with. However, in the interests of having the artifacts available should we choose to use them, this PR will prepare a set of artifacts which: * Disables incremental compilation unless the user has explicitly opted in (via an environment variable, for ease of setting it globally) * Adds the improved error message which tells the user how to workaround the breakage, intended for users who do explicitly re-enable incremental Note that the release notes mark Monday as the release date; I think it is likely that if we choose to go down this path we should indeed release on Monday, and potentially follow up in a week or two (e.g., May 20th) with a 1.52.2 if we have confidence in some collection of fixes. I think this will be unlikely, though. Please also note that this PR breaks normal policy by landing commits/work **only** on the stable branch. It is my intent to follow up with PRs toward beta and master, as well, but in the interests of making sure we have artifacts as early as possible I am posting this first. It will also let us provide an ask for testing, via the dev-static bucket, sooner rather than later.
