feat(lsp): per-server features and code-action-kinds filter (#1099)

A [[language-servers]] entry (or languageServers.<name> in settings) can list features and code-action-kinds: capabilities outside features are dropped after initialize and from later registrations, publishDiagnostics and Inspect Code only use servers with diagnostics, and code actions are narrowed to the kept kinds (advertised kinds and answers both). No built-in definition uses them yet. First stage of #901: lets a refactoring-only server sit next to the language's own one.
