Add new pixman_image_create_bits_no_clear() API

When pixman_image_create_bits() function is given NULL for bits, it
will allocate a new buffer and initialize it to zero. However, in some
cases, only a small region of the image is actually used; in that case
it is wasteful to touch all of the memory.

The new pixman_image_create_bits_no_clear() works exactly like
_create_bits() except that it doesn't initialize any newly allocated
memory.
