feat: state, store and starter-kit schematics support a project option

[profanis]

When we use the schematics to create

• state
• store
• starter-kit

we can rely on the project type and have the spec files with either provideStore() or NgxsModule.forRoot() if it's a standalone or not.

Furthermore, if we have a mono-repo workspace we can provide the project where we want to have the schematic run.

@profanis Great work!!!
The only thing missing is an update to the changelog.md file describing these changes.
But, I'll merge without it so that you don't have to dismiss the existing reviews.
