Handle insufficient margin for option exercise

[jhonabreul]

Description

Handling insufficient margin for automatic option exercise, which was causing the "Duplicated option assignment..." exception mentioned in the related issue #7815.

With these changes, simulated option exercises are handled using the Brokerage.OptionNofication event to create the option exercise order instead of going through the order processor, so that the margin check is bypassed and the order is placed and filled. After this, we expect a margin call like shown in the new regression algorithm InsufficientBuyingPowerForAutomaticExerciseRegressionAlgorithm.

Note: about algorithm's stats change (orders hash): since simulated options exercises are now handled like expired options exercise, without going throught the order processor to place them, some order properties are not populated, like OrderSubmissionData and PriceCurrency, but this should be taclked in a separate PR to keep this clean.
