feat: expose all options to packaging and publishing APIs

[nhedger]

This PR introduces modifications to allow the API methods to use all options currently supported by the CLI.

The following modifications have been made:

Packaging

1. The createVSIX function now accepts an IPackageOptions instead of ICreateVSIXOptions
2. The existing ICreateVSIXOptions has been kept in the file and refactored to stay backward compatible.
3. The ICreateVSIXOptions has been marked as deprecated to encourage using IPackageOptions instead.

Publishing

1. The publishVSIX function still accepts an IPublishOptions but it's currently an alias to the IPublishOptions type declared in publish.ts
2. The IPublishVSIXOptions has been refactored to extend from IPublishOptions and also includes the needed target property.

This should in theory be backward compatible because all existing types can still be imported and they were subsets of the types declared for the CLI.

Todo

• Move documentation comments to their respective interfaces

@nhedger Still draft?

I'll have a look this weekend. I don't remember from the top of my head if I had anything more to do.

Alright, seems good to review.

The IListFilesOptions could probably use some similar refactoring too, but I may do that in a future PR.
