rust deps: bump crypto/encoding

What

Upgrade the kernel_sdk, and all dependents to the latest version of tezos_crypto_rs/tezos_data_encoding.

Other places in the monorepo that do not depend on the SDK are unaffected (e.g. contrib/mir, which will be upgraded separately).

Fixes RV-13

Why

There are a number of updates in those two crates, including:

• bringing signatures into alignment with how they are performed in tezos_crypto (e.g. inputs are hashed prior to signing/verifying)
• removing possible errors from some b58check/hashing functions
• ensuring that hashes are always the correct length by construction.

See the full v0.6.0 CHANGELOG for more details

Upgrading the usage of these dependencies in tezos/tezos paves the way to move those two crates (plus tezos_data_encoding_derive into the monorepo), which will allow tighter integration/improvements/synergy between those crates, and places such as the rollup SDK.

How

The MR is split into several commits, so that various teams/groups may review parts relevant to them.

Kernel SDK

Everyone reviewing this MR should review this commit. NB this is a 'minimal' effort - ie bringing existing code up to date. Other possibilities (such as adding an impl NomReader for InboxMessage are left to the future).

RiscV/RustDeps

Only needs to be reviewed by the riscv crew.

Etherlink

To be reviewed by the Etherlink crew - the main things to watch out for are:

• no longer hashing messages signed by the sequencer, as this has been moved into the verify_signature functions
• the replacement of Signature by UnknownSignature, which is functionally equivalent. Signature would now refer to the aggregate signature type (which more closely aligns with tezos_crypto).

Kernel/Examples

Feel free to review, this brings the various 'example' kernels used in CI up to date - e.g. tx_kernel/dal_echo etc

Jstz

This is bumped to refer to a branch that itself contains the updates. That branch circularly refers to this one, and vice versa. Once this MR is merged - the jstz branch can be merged, referring to tezos/tezo master, and finally there will be a small MR back here to point back to jstz main. The relevant diff can be found here, and may be instructive reviewing for the riscv crew

Manually testing the MR
