What this really does is avoids shadowing names, so that we can comfortable have things like `Check::DiagnosticEmitter` or `Check::DiagnosticLoc` without shadowing being a concern. Note, down this path I'm also thinking about: - Renaming misc DiagnosticConsumer/DiagnosticEmitter classes, possibly just to DiagnosticConsumer/DiagnosticEmitter (so `Check::DiagnosticEmitter` instead of `SemIRLocDiagnosticEmitter`). - Dropping `Diagnostic` from `Emitter::DiagnosticBuilder`. - But not for `Check::DiagnosticBuilder`, because `Check::Builder` would be ambiguous. - Renaming diagnostics/diagnostic_* to drop "diagnostic". [Discussion about SemIRLoc -> DiagnosticLoc](https://discord.com/channels/655572317891461132/655578254970716160/1353771570463768698) reminded me of this (in particular the older [Check::DiagnosticBuilder discussion](https://discord.com/channels/655572317891461132/655578254970716160/1344363562608627763)), but I'd only do that rename if there's matching consensus about a path forward where we keep SemIRLoc, and in a way that it's only ever used for diagnostics (the divergence from which is at the root of current LocId discussion). I'm trying to keep that separate from a namespace addition for clarity.
