d81f5d29fb sw_engine/math: fine-tuning optimization 
Try to minimize the use of sqrt() and arctan() calls
when possible. These calls can be relatively expensive
when accumulated within a single frame.

Also repalce the division with shift operation.
since split cubic function is one of the significant hot-spots
in the data processing, we could earn a noticable enhancement.

Tested on single thread local machine:

Lottie: 0.080 -> 0.052s (-0.028s)
Performance: 0.023 -> 0.022 (-0.001s)

4de2b953d1 sw_engine/math: Enhance trigonometric functions. 
Streamlining computations with floating-point operations in rotation
thereby improving 'thorvg' speed.

Also use the well-optimized posix math functions instead of
custom math.

Test on my local machine.
