[parser] Recover missing identifier in new style typedef

Before, when parsing a new style typedef without an identifier (e.g.
`typedef = whatnot`) it concluded that the token after the equal-sign
wasn't an equal sign an that it thus had to be an old style typedef,
followed by recovery there.

This CL makes the recovery insert an identifier after `typedef` (what
the recovery of the old style actually did too), and then parse it as a
new style typedef.

This causes the previous many errors to just be `Expected an identifier,
but got '='.`

It is furthermore verified that the parsing of such a case is ~the same
as when having an indentifier.

Fixes https://github.com/dart-lang/sdk/issues/56912
