test(motion): added performance benchmark for spring vs linear easing at 60fps

[tmdeveloper007]

Summary of What Has Been Done

Added with performance benchmarks comparing spring, linear, and easeInOut easing at simulated 60fps (16.67ms per frame).

Changes Made

• Created with 6 test cases:
  • Spring tick: measures average time per frame over 10,000 iterations, asserts < 1ms/frame
  • Linear easing: measures average time per frame over 10,000 iterations, asserts < 0.1ms/frame
  • easeInOut easing: measures average time per frame over 10,000 iterations, asserts < 0.1ms/frame
  • Spring reaches target within 60 frames at 60fps
  • Linear interpolation determinism check
  • easeInOut symmetry check

Impact it Made

• Documents expected performance envelope for CI regression checks
• Provides quantitative evidence of animation performance characteristics
• Validates spring convergence within one second at 60fps

Closes Karanjot786#3289.
