Uplift dependencies to polkadot-v0.9.42

[weezy20]

Notable changes :

• pallet-balances now has extra configuration : Holds and Freezes

impl pallet_balances::Config for Test {
	// -- Existing parameters --
	type HoldIdentifier = ();
	type FreezeIdentifier = ();
	type MaxHolds = ConstU32<0>;
	type MaxFreezes = ConstU32<0>;
}

• pallet-collective introduces a new parameter that will reject propasals if they exceed some threshold
• Collator selection operations can now be performed by StakingAdmin in addition to Root.
• pallet_xcm::Config takes a new param AdminOrigin set to Root
• Change in the runtime build script - Deactivates wasm-builder when compiling to wasm
