Summary: This fixes a reported resource leak (by coverity).
_pack_meshes_vertex_data allocates memory stored in 'vertices' however
vertices is never free'd unless count > 0

Summary:
When processing random data result of this function differs from C variant in more than 50% cases.
This difference is due to alpha calculation, in C code :
alpha = 256 - (*s >> 24)
in NEON:
"vmvn.u8 q4,q0 \n\t"
// ie ~(*s>>24) === 255 - (*s>>24)
We cant just add "1" as overflow will occur in case (*s>>24) == 0 (we use only 8 bit per channel in vector registers)
So here is the solution:
copy *d right before multiplication and add it to the result of it later.
Same approach as in D455.

Make sure not to sample the mask image outside its boundaries.
This is a series of last resort checks. I can not reproduce the
crashes but know they have happened.
I used EINA_UNLIKELY more for clarity than for compiler optimizations.
As C version,
It increase alpha value by 1 to avoid loosing of the remains while it divides
values. Neon version does same technique to make same results.
This patch reduces power consumption by around 18mA in certain scenarios
(music player list scroll, my files sound list scroll), making
evas_common_convert_argb_premul() ~60% faster (6.2msec->2.6msec).
Take music-player application, make 100 copies of the standard
Over the Horizon” song, scroll up and down to see those
downscaled-from-720x720 thumbnails enter and leave the screen.
Every time a list item enters the screen, the image is re-read
(as evas image cache is not large enough to store more than two
pictures of that size), and one call of _common_convert_argb_premul()
occurs, taking ~6.2msec (which is not much compared to ~60msec
spent in libpng->libz (the biggest bottleneck here),
but still noticeable).
A similar power consumption improvement is observed during
scrolling sounds list of the same files in My Files application
(just with idle level ~100mA lower).
We also checked the new code to be correct on random input data.
all tests are performed based on tizen device.

prev logic increased the alpha channel by 1 so the unpremul resulted in the color got too diff from the origin.
We can't avoid losing the rest values while dividing values in premul/unpremul()
but this will recover the value better closed to origin value.
Summary:
Add pointer to target billboard node in Evas_3D_Node
Skip set flags change orientation for billboard node
Add method node_billboard_update to use it for change orientation during traverse
by nodes
Split API evas_3d_node_look_at_set to have possibility change orientation of node
without set flags
