## Description 

Add support for `public struct` declarations in the Move 2024 edition.

To my knowledge this is the first backwards incompatible change, so we
need to split off a separate version of the move-stdlib that tracks the
new 2024 edition as well.

The bottom commit of this PR does this, and also refactors the test
runner so we aren't passing so many fields all the time in the test
runner.

## Test Plan 

Added additional tests.

### Release notes

Adds initial `public struct` type visibility support to Move 2024.alpha.
When using the Move 2024.alpha edition you will be required to write
`public` in front of the struct type which will keep the same semantics
as `struct` with no visibility modifiers today (i.e., in the `legacy`
edition), this is to allow for future support of private struct types.
