Data types can define how they update security cache

Expected Behavior

• Data sources can define a way to update the security cache price properties

See related https://github.com/QuantConnect/Lean/pull/7808

Actual Behavior

Not possible. Security cache class knows how to handle trade/tick/quote bars, does not how to handle python data for example

Potential Solution

• We can create a base virtual function in BaseData class
• override in quotebar/tradebar and tick, this would just be moving the code from the security cache into each specific data type
• at this point custom data sources in python could define their own implementation. We could explore adding a helper method for o/h/l/c/v just to make users life easier

Checklist

• I have completely filled out this template
• I have confirmed that this issue exists on the current master branch
• I have confirmed that this is not a duplicate issue by searching issues

Start by locating BaseData and SecurityCache, then inspect how trade bars, quote bars, and ticks currently update security-cache price properties. The change is complete when custom data sources, including Python data, can define their own cache update behavior while existing data types retain their handling.
