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.

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.

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.
This PR adds 3 behaviors to the `pretty.Formatter` type.
1. A inner string method that accommodates state.
2. A visit function that allows pre-processing to discover recursive
types and apply tags to them.
3. A hash function that allows structural hashing on recursive types.
Together, this allows pretty-printing recursive types, regardless of
the pointers are. This allows `(0x1)Object{ key: *0x1 }` to be the same
as `(0x1)Object{ key: (0x2)Object{ key: *0x1 }}`.
Turn on pretty printing of types in all cases
Speed up printing by memoizing object hashes
