Removal of 'set_balance_deprecated' and 'transfer' dispatchables from TFChain

[sameh-farouk]

Just a heads up: The set_balance_deprecated and transfer dispatchables in the pallet_balances have been deprecated in paritytech/substrate#12951 and completely removed in polkadot-sdk v1.2.0. Instead, force_set_balance and transfer_allow_death should be used, respectively.

@renauter working to incorporate the latest polkadot-sdk updates for improved security, reliability, and bug fixes into tfchain. These breaking changes from polkadot-sdk v1.2.0 will be included in the upcoming 3.16 release.

Anything using tfchain-go-client and tfchain-js-client for making calls shouldn't need to adjust, as the changes should be covered in these clients.
However, services/sdks/frontends that use these dispatchables directly will need to be prepared to make adjustments.
