feat: add community cdp repay debt proposal (#1565)

* add CommunityPoolCDPRepayDebtProposal proto & type * add cdpKeeper to x/community's keeper * add handler for CommunityPoolCDPRepayDebtProposal * more test cases * rename CommunityPoolCDP -> CommunityCDP the proposal does not interact with the vanilla community pool * fix & test stringer * update changelog
