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
