feat: compute idle power with core ratio

[sunya-ch]

This patch is for adding an idle power based on ratio of the machine cores over the cores of the machine that is used for training the power model.

This PR can be merged independently but there is no core ratio set yet.

For local regressor core ratio, need the following Kepler PR to solve the TODO.

• feat: add machine spec generator/reader for model weight request #1684

For sidecar estimator, need the following PR in kepler-model-server to have estimator provides machine spec and server API to put machine spec to weight response.

• feat: add machine_spec to metadata kepler-model-server#405

Here is a concise summary of the pull request changes:

Summary: This pull request introduces a new feature to improve idle power estimation by considering the core ratio of the machine used for training the power model. Key modifications include:

• Adding coreRatio fields to Regressor and EstimatorSidecar structs
• Updating getWeightFromServer, GetPlatformPower, and GetComponentsPower methods to incorporate coreRatio parameter
• Modifying GetComponentPower and GetPlatformPower functions in utils package to accept coreRatio parameter
• Adding a new GetCoreRatio function to return the core ratio for idle power estimation

Impact: These changes may affect calling or dependent code, particularly in areas where Regressor and EstimatorSidecar structs are used. The external interface and behavior of the code are also affected, as the power estimation functionality has been modified.

Observations: The changes are well-organized and grouped by functionality, making it easier to understand the impact of each modification. However, it would be beneficial to include additional comments or documentation to explain the reasoning behind the changes and how they improve idle power estimation.
