max_individual_message on xcmp_queue too low for reserve relayed reserve-backed transfers between parachains

[JuaniRios]

Trying to send DOT from parachain A to parachain B through statemint, causes the message to be put in the statemint overweight queue due to a low limit of the config max_individual_message on the xcmp_queue pallet.

The message I'm trying to send is:

let transfer_xcm: Xcm<PolimecCall> = Xcm(vec![
    WithdrawAsset(vec![dot.clone()].into()),
    BuyExecution { fees: execution_dot.clone(), weight_limit: Limited(MAX_XCM_WEIGHT) },
    InitiateReserveWithdraw {
        assets: All.into(),
        reserve: MultiLocation::new(1, X1(Parachain(statemint_id()))),
        xcm: Xcm::<()>(vec![
        BuyExecution {
            fees: execution_dot.clone(),
            weight_limit: Limited(MAX_XCM_WEIGHT),
        },
        DepositReserveAsset {
            assets: All.into(),
            dest: MultiLocation::new(1, X1(Parachain(penpal_id()))),
            xcm: Xcm::<()>(vec![
                BuyExecution {
                    fees: execution_dot.clone(),
                    weight_limit: Limited(MAX_XCM_WEIGHT),
                },
                DepositAsset {
                    assets: All.into(),
                    beneficiary: X1(AccountId32 { network: None, id: ALICE.into() })
                        .into(),
                },
            ]),
        },
        ]),
    },
]);

Another problem is that I cannot take the coded version of this message from PolkadotJS and then paste it later on to get it back, because it says its too long.

Should be fixed by https://github.com/paritytech/polkadot/pull/6271/ that is merging EOW.
