[13.x] Add additional Artisan attributes for usage, help, hidden and isolated

[ziadoz]

This PR extends the PHP attribute support added in #58578 to cover $help, $hidden, $isolated/$isolatedExitCode on Artisan commands, via new #[Help], #[Hidden] and #[Isolated] attributes.

It also adds a #[Usage] attribute, for providing examples of how commands can be used when using --help.

#[Signature('example:cmd {user} --force')]
#[Description('An example Artisan command')]
#[Help('Performs imaginery work for the purposes of demonstration.')]
#[Hidden]
#[Isolated(exitCode: 1)]
#[Usage('example:cmd 1')]
#[Usage('example:cmd 1 --force')]
class ExampleCommand extends Command
{
    public function handle(): void {}
}
