This PR ensures that names suggested by tactics like `simp?` are not shadowed by auxiliary declarations in the local context and that names of `let rec` and `where` declarations are correctly resolved in tactic blocks. This PR contains the following potentially breaking changes: * Moves the `auxDeclToFullName` map from `TermElab.Context` to `LocalContext`. * Refactors `Lean.Elab.Term.resolveLocalName : Name → TermElabM …` to `Lean.resolveLocalName [MonadResolveName m] [MonadEnv m] [MonadLCtx m] : Name → m …`. * Refactors the `TermElabM` action `Lean.Elab.Term.withAuxDecl` to a monad-polymorphic action `Lean.Meta.withAuxDecl`. * Adds an optional `filter` argument to `Lean.unresolveNameGlobal`. Closes #6706, closes #7073.

# `simp?`-suggested names conflicting with auxiliary declarations

This test ensures that "unresolved" names provided by `simp?` do not conflict with local auxiliary
|
|
declarations.
