Remove Msf::Framework::VersionAPI and Msf::Framework::VersionCore

[MSP-10998](https://jira.tor.rapid7.com/secure/RapidBoard.jspa?rapidView=84&view=detail&selectedIssue=MSP-10998)

Remove `Msf::Framework::VersionAPI` and `Msf::Framework::VersionCore` because they can't handle minor version being 10 or higher, which means `Msf::Framework::VersionCore` is incompatible with `4.10.0`.
