Solana MCMS supported tx capacity [NONEVM-1069]

[jadepark-dev]

This PR analyzes transaction size limitations for the Solana MCMS programs

Primary Changes

• Added transaction size analysis for MCMS execution scenarios using two approaches:

  • Using memo program to test raw instruction data capacity
  • Using token transfers with timelock to test multi-instruction batching capacity and account metadata limits

• Added comprehensive cases covering:

  • mcm::execute: spl-memo::newMemo memo sizes from 32 to 759 bytes(w/o overheads) for instruction data limits
  • mcm::execute{timelock::schedule_batch}/timelock::execute_batch: Token transfer batches up to 16 transfers(1094 bytes w/o overheads) for throughput testing

• Added test summary logging for size analysis results

Others

• Enhanced RPC error helper to support transaction modifiers
• Added parallel execution to existing test cases for better test performance
