added |json filter with context-aware encoding

New |json filter (Helpers::encodeJson(), refactored out of escapeJs()
without the HtmlStringable unwrap branch). As the last filter in a chain
it carries a special, context-dependent meaning:

- HTML attribute as a whole value (via ExpressionAttributeNode), e.g.
  `data-x={$arr|json}`, routes to HtmlHelpers::formatJsonAttribute(),
  the same JSON + smart-quoting mechanism used by formatDataAttribute().
- JavaScript context (a <script> element, an on* attribute, or a JS
  content-type template, detected via Escaper::isJavaScript()) drops
  |json in PrintNode: escapeJs() already encodes to JSON there, so the
  filter is redundant and would otherwise double-encode. Dropped only
  when auto-escaping applies, so |json|noescape keeps it.
- Everywhere else (HTML text, XML, ...) |json runs as a regular filter
  and its output passes through the normal escaper, so '<', '>', '&' and
  quotes stay escaped.

Not being last, |json is a plain filter with no special handling. Both
nodes special-case it without mutating the AST: they clone the modifier
before removing the filter.
