feat(physics): Enhance physics bridge service with new functionalities

- Added SetGravity method to adjust the gravity in the physics world.
- Introduced AddSphereRigidBody method for creating sphere rigid bodies.
- Implemented RemoveRigidBody method to delete existing rigid bodies.
- Added SetRigidBodyTransform method to update the position and rotation of rigid bodies.
- Included ApplyForce and ApplyImpulse methods for applying forces and impulses to rigid bodies.
- Added SetLinearVelocity method to set the linear velocity of rigid bodies.
- Enhanced StepSimulation method to accept a maxSubSteps parameter.
- Implemented GetBodyCount method to retrieve the number of rigid bodies in the world.
- Added Clear method to remove all rigid bodies from the physics world.
- Updated the script engine service to bind new physics methods to Lua.
- Enhanced material configuration handling in shader script service.
- Introduced MaterialXMaterialConfig structure for better material management.
- Added texture binding support in ShaderPaths structure.
- Included stb_image implementation for image loading support.
