Allows using `--debug` to enable debug logging under
any subcommand. Currently it needed to be set as
`docker --debug buildx` meaning only way to enable debug
in standalone mode was to set env variable instead and
updating existing commands to add `--debug` was cumbersome.

Use the usage output of `--help` for each subcommand, to make
sure all flags/options are included on the page, and to make
it easier to keep docs in sync.
Note that the usage output is only used when reading these
docs on GitHub; docs.docker.com only consumes the "description"
and "example" sections (when present), and generates flag information
and usage output from source
