fix: engines not starting properly in msfs 2024

[Saschl]

Fixes #[issue_no]

Summary of Changes

execute_calculator_code does not seem to work properly in this case (and is discouraged anyway). Replaced with trigger_key_event (deprecated but working in both sims), which brings the correct behaviour back again.

Testing instructions

1. Spawn C&D in both sims ideally and perform engine starts with APU and ASU. N2 should rise quickly after engine master switches have been turned on

Does this only apply to Rust code or also to C++ code? execute_calculator_code is used extensively there

Will need to check that as well 👍 Most of the calls do not seem to take parameters which seems to work fine, but I haven't checked very thoroughly yet
