Problem
For SIMD-0177, we are going to introduce a new account layout for program-runtime, which will hold ownership of the
Arc<Vec<u8>>.After the transaction finishes, we want to reconstruct the
AccountSharedDatato be used again in the rest of the validators, while maintaining the same Arc reference.Solution
Implement a function to allow the creation of
AccountSharedDatawith an existing instance of the Arc.
