feat(release): add support for version plans

[fahslaj]

This PR adds support for "version plans", which is Nx Release's way of decoupling the release process from git history.

TODO on this PR:

• Add command for creation of version plans
• Test flow when using "release" top level command
• Test flow when using programmatic API to apply version plans
• Test flow for using version/changelog subcommands
• Move "firstRelease" out of general release options so that it doesn't appear for the plan command
• Do not generate version plan files with the implicit default group name (use project names instead? Or more friendly group identifier?)
• Export the releasePlan(...) function so that it's formally part of the programmatic api
• Implement a way to pass bump selections directly into command to bypass enquirer prompts (useful for testing and to allow users to use the releasePlan(...) programmatic api to overlay their own UX)
• Add e2e tests for "plan" command
• Write full PR writeup describing all version plan functionality
• Add guide for using version plans to docs
