[Forge test][Cheatcode support] `vm.load`

[pkhry]

Description

Implement vm.load cheat code for forge test in resolc mode.
function to read storage is inside pallet-revive::Pallet::get_storage().

relevant files are:

• crates/revive-strategy/src/cheatcodes/mod.rs implementation of cheatcode handler, magic happens here
• crates/forge/tests/cli/revive_vm.rs - add a test for load here to check that state for a sample contract(can be just a dummy contract with a constructor arg to set one the variables to a certain value) is initialized and can be loaded correctly. (maybe forge fuzz test ?)
