This PR adds support for marking options as deprecated. When a deprecated option is used via `set_option`, a warning is emitted (controlled by `linter.deprecated.options`). An `OptionDeprecation` structure with a required `since` field and an optional `text?` field is added to `OptionDecl`. Each `set_option` elaborator (command, term, tactic, grind) calls `checkDeprecatedOption` to emit warnings. The C++ `register_option` is updated to account for the new field. As a first use, `backward.eqns.nonrecursive` and `backward.eqns.deepRecursiveSplit` are marked deprecated. Continues earlier work done in #11096.
