  [lldb] Add an artifact provider mechanism to Diagnostics (#210417)

Add a hook that lets a subsystem contribute a file to the diagnostics
bundle, without breaking layering and making Core depend on it. A plugin
registers an ArtifactProvider callback and a file name via AddArtifactProvider.
Providers run when a bundle is collected, and each one that yields
content is written into the bundle and recorded in the report's
attachments.

This restores, in a simpler form, the collection point that the removed
Diagnostics callback mechanism offered. The motivating consumer is the
downstream Swift health check, which registers a provider to write its
"swift-healthcheck.log" into the bundle. Unlike the old callback, a
provider does not open or write its own file: it just returns the
contents as a string and Diagnostics handles the rest.
