Refactor ConsoleArguments to use in-class initializers and remove redundant = operator (#962)

[MichaelK05-dev]

Summary of the Pull Request

This PR refactors the ConsoleArguments class to use in-class member initializers for members with constant or default values, replacing equivalent entries in the constructor initializer list.

This change aligns the class with C++ Core Guidelines C.48 (“Prefer in-class initializers to member initializers in constructors for constant initializers”) while preserving existing behavior.

References and Relevant Issues

Detailed Description of the Pull Request / Additional comments

src/host/ConsoleArguments.hpp

• Added in-class default member initializers for members previously initialized with constant values.
  Examples include:
  _headless,
  _width,
  _height,
  _forceV1,
  _runAsComServer,
  _forceNoHandoff
• make operator= default

src/host/ConsoleArguments.cpp

• Removed redundant constructor member initializers corresponding to the in-class defaults.
• Members that depend on constructor parameters remain in the initializer list.
• Removed =operator as it is no longer needed since the default copy assignment operator performs the exact same now.

Validation Steps Performed

Manual Verification

• Performed strict code inspection to ensure a one-to-one correspondence between removed constructor initializers and added in-class initializers.
