[WIP] flamenco, vm: implement increase_cpi_account_info_limit

[topointon-jump]

Implementing increase_cpi_account_info_limit (solana-foundation/solana-improvement-documents#339), which improves UX/reduces work for programs which make CPI calls that were themselves invoked with more than 64 accounts - they no longer have to de-dup the list of account infos to make a CPI call.

This SIMD also starts charging for serialized account infos and instruction account metas in CPIs.
