[0.6.173] Change to convert and rotate image with mm_util_image_h

- Changed function
 : mm_util_convert_image(), mm_util_rotate_image()
- These functions convert & rotate mm_util_image_h image with format & rotation,
  it will return allocated mm_util_image_h image.
  before changing, it has too few parameter to check problem
  like buffer overflow.
  So, change parameter to mm_util_image_h with mandotory information.
