This updates the platforms package to be an alias for the new platforms module.
This helps transitioning consumers to the new module, and makes sure that
containerd v2 and v1 use the same definitions.

Import the log module directly, instead of using the aliases that are
provided in the log package. This helps find code-paths that still depend
on the old location, and that haven't migrated yet to the new module.

Print deprecation warnings on any ctr command, as users won't notice the
deprecations until we actually remove the deprecated features.
The warnings can be suppressed by setting
`CONTAINERD_SUPPRESS_DEPRECATION_WARNINGS=1`.

This is effectively a revert of 2ac9968401, which
switched from os/exec to the golang.org/x/sys/execabs package to mitigate
security issues (mainly on Windows) with lookups resolving to binaries in the
current directory.
from the go1.19 release notes https://go.dev/doc/go1.19#os-exec-path
> ## PATH lookups
>
> Command and LookPath no longer allow results from a PATH search to be found
> relative to the current directory. This removes a common source of security
> problems but may also break existing programs that depend on using, say,
> exec.Command("prog") to run a binary named prog (or, on Windows, prog.exe) in
> the current directory. See the os/exec package documentation for information
> about how best to update such programs.
>
> On Windows, Command and LookPath now respect the NoDefaultCurrentDirectoryInExePath
> environment variable, making it possible to disable the default implicit search
> of “.” in PATH lookups on Windows systems.

From golangci-lint:
> SA1019: rand.Read has been deprecated since Go 1.20 because it
>shouldn't be used: For almost all use cases, crypto/rand.Read is more
>appropriate. (staticcheck)
> SA1019: rand.Seed has been deprecated since Go 1.20 and an alternative
>has been available since Go 1.0: Programs that call Seed and then expect
>a specific sequence of results from the global random source (using
>functions such as Int) can be broken when a dependency changes how
>much it consumes from the global random source. To avoid such breakages,
>programs that need a specific result sequence should use
>NewRand(NewSource(seed)) to obtain a random generator that other
>packages cannot access. (staticcheck)

The `ctr image usage` can display the usage of snapshots with a given
image ref. It's easy for user to get chain snapshot IDs and unpack
usage. And according to the [discuss][1], this subcommand can be used to
ensure if snapshot's pagecache has been discarded in a unexpected
reboot.
How to use it:
```bash
$ bin/ctr image usage --snapshotter native docker.io/library/golang:1.19.3
ctr: image docker.io/library/golang:1.19.3 isn't unpacked in snapshotter native
$ bin/ctr image usage --snapshotter overlayfs docker.io/library/golang:1.19.3
