RSDK-9288: declutter UI

[purplenicole730]

Changes:

• hide help command for all commands with a subcommand list
• fix incorrect usage text and remove arguments from usage text
• standardize usage text to better reflect what's required and optional
• remove arguments and replace with flags, keep backwards capability

Most of the changes can be shown through the following examples.
Before: command is unclear if it's supposed to be replaced or not, and arguments is misleading

rdk % go run ./cli/viam --help                 
USAGE:
   viam [global options] command [command options] [arguments...]

After: remove arguments and highlight command is something to replace:

rdk % go run ./cli/viam --help
USAGE:
   viam [global options] <command> [command options]

Before: ignores login options and ignores that command is optional

rdk % go run ./cli/viam login --help
USAGE:
   viam login command [command options] [arguments...]

After: alludes to login options and command is now optional

rdk % go run ./cli/viam login --help
USAGE:
   viam login [options] [command] [command options]

Before: Incorrectly shows additional options and arguments when there are none

rdk % go run ./cli/viam login print-access-token --help
USAGE:
   viam login print-access-token [command options] [arguments...]

After: Show clear and correct usage

rdk % go run ./cli/viam login print-access-token --help
USAGE:
   viam login print-access-token

Before: incorrect command name and alludes to nonexistent other options

rdk % go run ./cli/viam organizations auth-service enable --help
USAGE:
   viam enable --org-id=<org-id> [other options]

After: correct way to use command

rdk % go run ./cli/viam organizations auth-service enable --help
USAGE:
   viam organizations auth-service enable --org-id=<org-id>

Before: shows wrong usage of org-id flag and ignores subcommands

rdk % go run ./cli/viam organizations logo --help
USAGE:
   viam organizations logo --org-id=<org-id> [other options]

COMMANDS:
   set      set the logo for an organization from a local file
   get      get the logo for an organization
   help, h  Shows a list of commands or help for one command

After: correct usage of logo without flags and with subcommands. hides help subcommand

rdk % go run ./cli/viam organizations logo --help               
USAGE:
   viam organizations logo <command> [command options]

COMMANDS:
   set  set the logo for an organization from a local file
   get  get the logo for an organization

Before: Alludes to command options that don't exist, inconsistent org argument

rdk % go run ./cli/viam locations list --help
USAGE:
   viam locations list [command options] [organization]

OPTIONS:
   --help, -h  show help (default: false)

After: add org flag, remove arguments suggestion

rdk % go run ./cli/viam locations list --help
USAGE:
   viam locations list [options]

OPTIONS:
   --organization value, --org value, --org-id value, --org-name value  (default: first organization alphabetically)

Test to make sure:

• default continues working
• flag works
• argument works for backwards capability
• flag takes priority over argument

rdk % go run ./cli/viam locations list                     
Locations for "<>":
<>:
        First Location (id: <>)
rdk % go run ./cli/viam locations list --organization "<>"
        First Location (id: <>)
rdk % go run ./cli/viam locations list "<>"               
        First Location (id: <>)
rdk % go run ./cli/viam locations list --organization "<>" "fake"
        First Location (id: <>)
