Remove index_in_callee from InstructionAccount

[LucasSte]

Problem

In SIMD-0177, we want InstructionContext to have only index_in_transaction, is_signer and is_writable. We must, then, remove index_in_callee.

Summary of Changes

1. Use the duplication map created in prepare_next_to_level_instruction, and in prepare_next_instruction for detecting duplicated accounts and retrieving the index_in_instruction from the index_in_transaction.
2. fn configure now receives the aforementioned map as an argument, so I crated fn configure_for_test to facilitate the usage in tests.
3. Add tests to ensure the functionality is correct.

[mergify]

The Firedancer team maintains a line-for-line reimplementation of the
native programs, and until native programs are moved to BPF, those
implementations must exactly match their Agave counterparts.
If this PR represents a change to a native program implementation (not
tests), please include a reviewer from the Firedancer team. And please
keep refactors to a minimum.
