[loader-v2] Refactor how environment is stored in unsync storages and remove V1 from tests

[georgemitenkov]

Description

This PR refactors UnsyncModuleStorage and UnsyncCodeStorage so that they do not own the runtime environment. The goal is to make them stateless, which would allow us to get rid of clones and Arcs for AptosEnvironment. Currently, this is tricky to do because storages consume the environment clone.

On this PR:

• Changed InMemoryStorage to also store environment. This is helpful because it allows to store deserializer config inside, which is needed anyway. This way storage interfaces are unified: adapter, Block-STM's latest view and this - all store a reference to some bytes + environment.
• Changed StateViewAdapter to also store environment.
• Removed environment from Unsync...Storages because now it is provided by the trait bound on S: ... + WithRuntimeEnvironment. This way we do not need to own it there. Moved tests to integration-tests/code_storage_tests.rs.
• Adapted all tests to work with that. Things become cleaner!

Bonus: as loader V2 is default, removed legacy V1 flows. For loader_tests.rs in integration-tests I think we can remove some (cc @vgao1996) because size check is removed. For concurrent tests, will bring them back separately (tracked as a TODO).

How Has This Been Tested?

Existing tests, this PR just moves some code around.
