Add a utility for completing platform strings.
Platforms offers completion for platform-strings. It provides a non-exhaustive
list of platforms to be used for completion. Platform-strings are based on
[runtime.GOOS] and [runtime.GOARCH], but with (optional) variants added. A
list of recognised os/arch combinations from the Go runtime can be obtained
through "go tool dist list".
Some noteworthy exclusions from this list:
- arm64 images ("windows/arm64", "windows/arm64/v8") do not yet exist for windows.
- we don't (yet) include `os-variant` for completion (as can be used for Windows images)
- we don't (yet) include platforms for which we don't build binaries, such as
BSD platforms (freebsd, netbsd, openbsd), android, macOS (darwin).
- we currently exclude architectures that may have unofficial builds,
but don't have wide adoption (and no support), such as loong64, mipsXXX,
ppc64 (non-le) to prevent confusion.

It's an alias for cobra.FixedCompletions but takes a variadic list
of strings, so that it's not needed to construct an array for this.

EnvVarNames offers completion for environment-variable names. This
completion can be used for "--env" and "--build-arg" flags, which
allow obtaining the value of the given environment-variable if present
in the local environment, so we only should complete the names of the
environment variables, and not their value. This also prevents the
completion script from printing values of environment variables
containing sensitive values.
For example;
export MY_VAR=hello
docker run --rm --env MY_VAR alpine printenv MY_VAR
hello
Before this patch:
docker run --env GO
GO111MODULE=auto GOLANG_VERSION=1.21.12 GOPATH=/go GOTOOLCHAIN=local
With this patch:
docker run --env GO<tab>
GO111MODULE GOLANG_VERSION GOPATH GOTOOLCHAIN

This is just a convenience function to allow defining completion to
use the default (complete with filenames and directories).

The completion functions only need the API-client, and not all of
the CLI. However, passing the API-client as argument would mean
that the API-client is initialized early, which may not be what
we want, so instead, defining an APIClientProvider interface to
preserve the behavior of initializing when needed only.
While updating, also simplify stack.format to only require an
io.Writer.
