Override JS player/vehicle GetScale/SetScale methods to only use scalar float

[zpl-zak]

Issue Description

• The current framework codebase uses a Vector3 structure to specify the scale of entity.
• MafiaMP relies on a scalar floating point value for model scale, which means it uses uniform scaling.

Action Items

• [ ] Override the setScale and getScale functions within the scripting engine to operate only with scalar floating point values.
• [ ] Reuse one of the Vector3's three components as a storage for the scalar value.
• [ ] Ensure that MafiaMP applies the scalar value directly on the client side via an SDK call to scale the entity properly.
