Add combat system component to character

[TechGladiator]

Add a comprehensive combat system component to the plugin's character class, fully integrated with the Gameplay Ability System.

This PR introduces a robust combat system, including a ValorCombatComponent for core logic, ValorCombatData for configuration, a base ValorCombatAbility with several concrete abilities (Light Attack, Heavy Attack, Block, Dodge), and an example ValorCombatCharacter demonstrating its usage. It leverages the existing GAS setup for attribute management and ability activation.

@cursor new build errors:
ValorCombatComponent.h(132): Error: 'DealDamage' conflicts with 'Function /Script/ValorAbilitySystem.ValorCombatComponent:DealDamage'
ValorCombatComponent.h(135): Error: 'TakeDamage' conflicts with 'Function /Script/ValorAbilitySystem.ValorCombatComponent:TakeDamage'

I refactored the UValorCombatComponent to improve API clarity by renaming its generic DealDamage and TakeDamage functions to explicitly indicate physical damage. This makes the component's interface more intuitive for developers.

• I renamed the UValorCombatComponent::DealDamage(AActor* Target, float Damage) function to UValorCombatComponent::DealPhysicalDamage in both Source/ValorAbilitySystem/Private/ValorCombatComponent.cpp and Source/ValorAbilitySystem/Public/ValorCombatComponent.h.
• Similarly, I renamed UValorCombatComponent::TakeDamage(AActor* Source, float Damage) to UValorCombatComponent::TakePhysicalDamage across both Source/ValorAbilitySystem/Private/ValorCombatComponent.cpp and Source/ValorAbilitySystem/Public/ValorCombatComponent.h.
• I updated the comments in Source/ValorAbilitySystem/Public/ValorCombatComponent.h for these functions, clarifying them as "Convenience functions with default damage type" to better reflect their specific purpose.
