Sync with polkadot-sdk + migrate to Blake2x256 + storage deposit limit fixes

[cmichi]

The PR fixes our CI. It also:

• Synchronizes with polkadot-sdk/c40b36c3a7c208f9a6837b80812473af3d9ba7f7. There are some changes required for that.
• Migrates blake2_256 to use the new pallet-revive pre-compile.

Note:
We currently require users to juggle two different types when dealing with anything value. That's not our choice, but rather we just expose to the user which types pallet-revive wants.

• Balance is used when e.g. communicating with a node via the E2E API or setting storage deposit limits.
• U256 is used e.g. when the contract queries its own value or in a contract call trace.

This is unfortunate, as it requires applying the pallet-revive Config::NativeToEthRatio multiplication factor for converting between both types. We could just decide on one type (U256 as it allows for a bigger number range) and do the conversion in the background. I'm on the fence though as it could lead to user confusion when they e.g. view the contract balance on a third party interface or use a frontend library that doesn't do this.

The other thing worth mentioning is that I'll provide some abstractions around calling pre-compiles in a follow-up PR.

[davidsemakula]

Looks great overall!
A few suggestions and potential fixes noted below though.

[davidsemakula]

We could just decide on one type (U256 as it allows for a bigger number range) and do the conversion in the background.

One thing that speaks for the opposite direction (i.e. Balance as the one type), is that converting from Balance to U256 is presumably infallible, while U256 to Balance is a fallible conversion.

But yeah, it's a bit of a mess really.

[davidsemakula]

LGTM!
Great to finally have a stable Blake2x256!

One suggestion below though.
