Deprecate x/paramfilter in favor of ante handler

[rootulp]

Context

Binary Builders is working on upgrading the SDK to v0.52.x. See https://github.com/01builders/celestia-app/blob/sdk-v0.52.x/binary.md for progress updates

Problem

They're hitting an issue with the existing x/paramfilter

Goal #11: Wire circuit breaker to block some (staking & bank) MsgUpdateParams now that x/paramfilter is removed

Proposal

Refactor the x/paramfilter module to be an ante handler. The ante handler should reject txs that attempt to modify any of these governance params

celestia-app/app/app.go

Lines 766 to 779 in 29d4409

	// BlockedParams returns the params that require a hardfork to change, and
	// cannot be changed via governance.
	func (app *App) BlockedParams() [][2]string {
	return [][2]string{
	// bank.SendEnabled
	{banktypes.ModuleName, string(banktypes.KeySendEnabled)},
	// staking.UnbondingTime
	{stakingtypes.ModuleName, string(stakingtypes.KeyUnbondingTime)},
	// staking.BondDenom
	{stakingtypes.ModuleName, string(stakingtypes.KeyBondDenom)},
	// consensus.validator.PubKeyTypes
	{baseapp.Paramspace, string(baseapp.ParamStoreKeyValidatorParams)},
	}
	}
