Add zkSBTs

Description

SBT feature for Manta

Changes:

• Pulls types in MantaPay into a support crate for common use in pallet-manta-pay and pallet-manta-sbt
• Adds SBT functunality in pallet-manta-sbt
• Adds MantaSbt to Dolphin and Calamari runtime along with sbt rpc enpoints in each client

Workflow of pallet-manta-sbt:

MantaSbt has two calls reserve_sbt and to_private.

step 1: reserve_sbt

• Reserves unique AssetIds by incrementing NextSbtId
• Maps the above unique AssetIds to the polkadot address in ReservedId to whitelist that account. This allows this specific polkadot address to call to_private on those specific AssetIds

step 2: to_private

• Checks that caller has ReservedIds in storage. And ensures that the TransferPost is a ToPrivate corresponding to the correct AssetId from ReservedIds. Then it inserts metadata and UTXO into MantaSbt storage.

closes: #936

Before we can approve this PR for merge, please make sure that all the following items have been checked off:

• Connected to an issue with discussion and accepted design using zenhub "Connect issue" button below
• Added one label out of the L- group to this PR
• Added one or more labels from the A- and C- groups to this PR
• Explicitly labelled A-calamari, A-dolphin and/or A-manta if your changes are meant for/impact either of these (CI depends on it)
• Re-reviewed Files changed in the Github PR explorer.

Situational Notes:

• If adding functionality, write unit tests!
• If importing a new pallet, choose a proper module index for it, and allow it in BaseFilter. Ensure every extrinsic works from front-end. If there's corresponding tool, ensure both work for each other.
• If needed, update our Javascript/Typescript APIs. These APIs are officially used by exchanges or community developers.
• If modifying existing runtime storage items, make sure to implement storage migrations for the runtime and test them with try-runtime. This includes migrations inherited from upstream changes, and you can search the diffs for modifications of #[pallet::storage] items to check for any.

I guess you can put ignore on the fee test, we already have an issue.
