feat: add talosctl machineconfig patch command
Add talosctl machineconfig patch command which accepts a machine config as input and a list of patches, applying the patches and writing the result to a file or to stdout. Link `talosctl machineconfig gen` to `talosctl gen config`, so they work the same way. Closes siderolabs#6562. Signed-off-by: Utku Ozdemir <utku.ozdemir@siderolabs.com>
