Richard Smith 1b0a5709e6 Initial support for fn expressions. (#7893) ...

Support for `fn` expressions with the same feature set as `fn`
declarations. In particular, there is no support for captures,
positional parameters, `=>` bodies, or `auto` return types.

Note that this results in two parse nodes for each `=>` token. That's a
bug, but it matches the behavior of function declarations, and will be
fixed in a follow-up change.
