feat: Better formatting for AggregateError (#14285)

This commit adds "aggregated" field to "deno_core::JsError" that stores
instances of "JsError" recursively to properly handle "AggregateError"
formatting. Appropriate logics was added to "PrettyJsError" and
"console" API to format AggregateErrors.
