This resulted in the flags passed to rustc having random
ordering, see #3895.

The resolved features were returned in a HashSet and then iterated over,
which returns the feature names in arbitrary order.

See #3895

Deterministic -L and --cfg flag ordering

This ensures that the `-L` and `--cfg` flags passed to `rustc` have stable ordering across runs.

It also does the same for `--cfg` flags passed to `rustdoc`.

Fixes #3895

3360 - Allow for features to be either comma or space delimited.

Any suggestions you might have to improve the submission would be great.
Thanks!

In TOML we have to emit all keys before we emit all sub-tables, so to handle
that for dependencies just transform everything to an elaborated version.
