Create metadata claims package / remove from contractkit (#340)

### Description

@celo/contractkit has for a long time basically had within it a
subpackage under /identity that really didnt have anything to do with
contractkit. Removing it will make it easier to build social connect
tools as they use the IdentityMetadataMapper contained in here. However
this is not social connect tool so it will remain in the developer
tooling repo.

This is a prereq to remove contractkit as a dependency for social
connect. a long term aim.

### Other changes


### Tested

uses existing tests

### Related issues

### Backwards compatibility
nope
exports moved to a new package. file structure slightly altered.
parameter for IdentityMetadataMapper changes to take an object with
specific functions rather than a kit

## PR-Codex overview
This PR introduces the `@celo/metadata-claims` package, extracting
identity-related functionality from `@celo/contractkit`. This allows
developers to use the `IdentityMetadataWrapper` independently of
`ContractKit`, enhancing modularity and usability.

### Detailed summary
- Created `@celo/metadata-claims` package.
- Moved identity and claims-related functionality from
`@celo/contractkit`.
- Updated imports in CLI commands and SDK files to use the new package.
- Introduced types like `AccountMetadataSignerGetters`.
- Removed identity-related exports from `@celo/contractkit`.
- Added tests for new functionality in the `metadata-claims` package.

+Removes all exports under the lib/identity folder. These have been move to a new @celo/metadata-claims package and should be imported from there. 
+
+Note that folder structure is also flattened slightly. so replace `@celo/contractkit/lib/identity/claims/` with `@celo/metadata-claims/lib/`
+
+example
+
+```diff
+- import { createAccountClaim } from '@celo/contractkit/lib/identity/claims/account'
++ import { createAccountClaim } from '@celo/metadata-claims/lib/account'
+```
+
+```diff
+- import { ContractKit, IdentityMetadataWrapper, newKitFromWeb3 } from '@celo/contractkit'
+- import { ClaimTypes } from '@celo/contractkit/lib/identity'
++ import { ContractKit, newKitFromWeb3 } from '@celo/contractkit'
++ import { ClaimTypes, IdentityMetadataWrapper } from '@celo/metadata-claims'
+
+```
+
+Note that Contractkit is Not a dependency. Instead when using `IdentityMetadataWrapper`  you should make an object that satisfis the `AccountMetadataSignerGetters` type  
+
+```typescript
+import { AccountMetadataSignerGetters } from '@celo/metadata-claims/lib/types';
+
+```
+using viem it would be like 
+
+```typescript
+const accountsMetaDataSignerGetters: AccountMetadataSignerGetters = {
+      isAccount: async (address: string) => accounts.read.isAccount([address as Address]),
+      getValidatorSigner: async (address: string) =>
+        accounts.read.getValidatorSigner([address as Address]),
+      getVoteSigner: async (address: string) =>
+        accounts.read.getValidatorSigner([address as Address]),
+      getAttestationSigner: async (address: string) =>
+        accounts.read.getValidatorSigner([address as Address]),
+    }
