sdk/go: Move Output implementation to internal **Note to reviewers**: GitHub's PR view will show a lot more for this change than the actual code added/removed. Consider opening a `git diff` of this with, git diff -C --diff-algorithm=minimal This will correctly detect the bulk of the diff as "copy a file and delete a bunch of stuff from it." --- In preparation for implementing generic variants of Input and Output in a pulumix subpackage, move some of the requisite types to internal/ so that we don't have a cyclic dependency between pulumi and pulumix. This change is largely mechanical with adjustmenets made for compilation. For places in pulumi/ where internal state of an output was accessed, new top-level functions were added to internal/ that expose this information. Changes were noting explicitly: - `OutputState` was changed to record dependencies as `[]internal.Resource` instead of `[]Resource` because moving `Resource` into internal will end up moving most of pulumi/ into internal. We cast to/from internal.Resource as needed. - `internal.AnyOutputType` is a `reflect.Type` filled by sdk/go/pulumi at `init()` time. This is an annoying hack, but we can't move AnyOutput into internal. - `internal.FullyResolvedTypes` is similarly filled by sdk/go/pulumi at `init()` time. To add confidence to this change being safe, I used [apidiff] to compare the API of the go/pulumi package befor and after this change. The command reported no changes. [apidiff]: https://pkg.go.dev/golang.org/x/exp@v0.0.0-20230713183714-613f0c0eb8a1/cmd/apidiff On top of that, I also ran `go doc -all .` with the before/after and ran a text diff on the result. The following changes were reported: - `Input` is now an alias to `internal.Input` - `Output` is now an alias to `internal.Output` - `OutputState` is now an alias to `internal.OutputState` - `OutputState.ApplyT`, `OutputState.ApplyTWithContext` were deleted (except they're present on the alias so they're still available) - `Resource` now embeds `internal.Resource` Resolves #13585
