Cannot Specify Platform For Documents Generation

[justinguo]

Currently we cannot specify the build platform for swift-docc-plugin. This means that the generate-documentation command only generates documentation for macOS. We hope that in the future there can be a -platform flag to allow document generation for a specific platform.

Checklist

• If possible, I've reproduced the issue using the main branch of this package.
• This issue hasn't been addressed in an existing GitHub issue.

Expected behavior

There can be a -platform flag to allow document generation for a specific platform. For example, we can generate documents for iOS platform or tvOS platform.

Actual behavior

The generate-documentation command only generates documentation for macOS.

Steps to Reproduce

Run swift package generate-documentation, it is no possible to specify the platform information.
