Combination of a few cleanups.
1. Don't call .Error() on errors that are being passed to "%s" format
functions. Format will call `Error()` itself.
2. Don't call assert.Error then assert.Equal/Contains, just use
assert.ErrorEqual/ErrorContains instead.
3. Use "%w" if appropriate, instead of "%v"/"%s".

# Description
<!--- Please include a summary of the change and which issue is fixed.
Please also include relevant motivation and context. -->
This adds a new type `tokens.StackName` which is a relatively strongly
typed container for a stack name. The only weakly typed aspect of it is
Go will always allow the "zero" value to be created for a struct, which
for a stack name is the empty string which is invalid. To prevent
introducing unexpected empty strings when working with stack names the
`String()` method will panic for zero initialized stack names.
Apart from the zero value, all other instances of `StackName` are via
`ParseStackName` which returns a descriptive error if the string is not
valid.
This PR only updates "pkg/" to use this type. There are a number of
places in "sdk/" which could do with this type as well, but there's no
harm in doing a staggered roll out, and some parts of "sdk/" are user
facing and will probably have to stay on the current `tokens.Name` and
`tokens.QName` types.
There are two places in the system where we panic on invalid stack
names, both in the http backend. This _should_ be fine as we've had long
standing validation that stacks created in the service are valid stack
names.
Just in case people have managed to introduce invalid stack names, there
is the `PULUMI_DISABLE_VALIDATION` environment variable which will turn
off the validation _and_ panicing for stack names. Users can use that to
temporarily disable the validation and continue working, but it should
only be seen as a temporary measure. If they have invalid names they
should rename them, or if they think they should be valid raise an issue
with us to change the validation code.

If the change(s) in this PR is a modification of an existing call to the
Pulumi Cloud,
then the service should honor older versions of the CLI where this
change would not exist.
You must then bump the API version in
/pkg/backend/httpstate/client/api.go, as well as add
it to the service.

- [ ] Yes, there are changes in this PR that warrants bumping the Pulumi
Cloud API version
<!-- @Pulumi employees: If yes, you must submit corresponding changes in

Previously, the error message was:
```
error: a stack name may only contain alphanumeric, hyphens, underscores, or periods
```
This wasn't great because it lacked specificity, but was especially bad if candidate stack
name was >100 characters or empty.
The new error messages are as follows:
1. If empty: "a stack name may not be empty"
2. If >100 chars: "a stack name cannot exceed 100 characters"
3. If it contains invalid characters: "a stack name may only contain alphanumeric,
hyphens, underscores, or periods: invalid character %q at position %d" (with the
appropriate values filled in).

Per team discussion, switching to gofumpt.
[gofumpt][1] is an alternative, stricter alternative to gofmt.
It addresses other stylistic concerns that gofmt doesn't yet cover.
[1]: https://github.com/mvdan/gofumpt
See the full list of [Added rules][2], but it includes:
- Dropping empty lines around function bodies
- Dropping unnecessary variable grouping when there's only one variable
- Ensuring an empty line between multi-line functions
- simplification (`-s` in gofmt) is always enabled
- Ensuring multi-line function signatures end with
`) {` on a separate line.
[2]: https://github.com/mvdan/gofumpt#Added-rules
gofumpt is stricter, but there's no lock-in.
All gofumpt output is valid gofmt output,
so if we decide we don't like it, it's easy to switch back
without any code changes.
gofumpt support is built into the tooling we use for development
so this won't change development workflows.
- golangci-lint includes a gofumpt check (enabled in this PR)
- gopls, the LSP for Go, includes a gofumpt option
(see [installation instrutions][3])

This change was generated by running:
```bash
gofumpt -w $(rg --files -g '*.go' | rg -v testdata | rg -v compilation_error)
```
The following files were manually tweaked afterwards:
- pkg/cmd/pulumi/stack_change_secrets_provider.go:
one of the lines overflowed and had comments in an inconvenient place
- pkg/cmd/pulumi/destroy.go:
`var x T = y` where `T` wasn't necessary
- pkg/cmd/pulumi/policy_new.go:
long line because of error message
- pkg/backend/snapshot_test.go:
long line trying to assign three variables in the same assignment
I have included mention of gofumpt in the CONTRIBUTING.md.

* Fix the nullability of config type properties in C# codegen (#4379)
The next change is going to do some code motion that would create some
circular imports if we did not do this. There was nothing that
required the members we were moving be in the backend package, so it
was easy enough to pull them out.
