Fix ignoring lambda expression in C++ plugin

[barnabasdomozi]

Previously, we calculated metrics for functions inside anonymous lambda objects. This has now been fixed.

Pull request overview

This PR fixes the cppmetrics-ignore-lambdas flag to properly exclude functions inside lambda objects from metrics calculations. Previously, function-level metrics (McCabe complexity and Bumpy Road) were incorrectly calculated for functions inside anonymous lambda objects.

Key changes:

• Added inLambdaObject field to CppFunction model to track if a function is inside a lambda
• Introduced getFunctionQuery() template method to apply lambda filtering when the flag is set
• Refactored typeMcCabe() to use CohesionCppRecordView for more consistent type querying
