`result.Result` is a type that was introduced to enable us to
distinguish between *expected* errors (or *bails* in Pulumi parlance)
and *unexpected* errors or exceptions. Prior to Go 1.13, this made a lot
of sense, since there was no standard story on "wrapping" errors, and
thus no way to answer the question "did I end up here (in an error path)
because I meant to, or did I end up here because of a program bug?".
With the introduction of `%w`, `interface { Unwrap() []error }` and
company in Go 1.13, a simpler interface is available: one can use
`errors.Is` and `errors.As` to ask if an error at any point wraps an
error of a certain type. With this, we can simply ask "is there a bail
at any point in this error tree?" rather than having to track this
explicitly using a type such as `result.Result`. The `IsBail` function
was introduced a while ago to this end, but its rollout was not
completed and several uses of `result.Result` remained.
This commit completes the rollout of this simplified interface,
replacing all uses of `result.Result` with native Go errors that may or
may not wrap bails, and all uses of e.g. `res.IsBail` with
`IsBail(err)`. Doing so allows us to remove `result.Result` entirely.
