Adds permissioned signer support

[kaw2k]

Description

This PR adds support for permissioned signers to the Aptos TS SDK.

Update: I added a unified permission class. You can see the diff of the change by looking at the commit history.

One design choice I would appreciate feedback on: The classes I created to represent permissions don't share a common parent. This impacts any wallet that needs to serialize requests before interfacing with nodes. For example, with aptos connect, this means that when requesting permissions from the wallet we need to separate the permission types in the request body. For example, here is how we request permissions in the dapp on aptos connect.

  const requestPermissionResponse = await dappClient.requestPermission({
    network,
    fungibleAssetPermissions: [
      new FungibleAssetPermission({
        amount: 100_000_000,
        asset: AccountAddress.A,
      }),
    ],
    gasPermission: new GasPermission({
      amount: 10_000_000,
    }),
  });

Note how the permissions are separated by type. If there was a common parent, we could have a single array of permissions like so:

const requestPermissionResponse = await dappClient.requestPermission({
  network,
  permissions: [
    new FungibleAssetPermission({
      amount: 100_000_000,
      asset: AccountAddress.A,
    }),
    new GasPermission({
      amount: 10_000_000,
    }),
  ],
});

Curious to hear opinions on this, if it is an issue or not.

Test Plan

There are a couple test cases I need to add after the issue with the script composer is resolved, mainly around the new gas permission. I have a little bit of cleanup to do in permissionedSigner.test.ts as well.

Outside of the test cases, the Aptos Connect PR has an e2e flow implemented for requesting permissions, and a dapp to consume the feature.
