[hal_h264e_vepu]: Fix stride parameter compatible

Browse Source 
Fix stride definition to compatible to both pixel stride and byte
stride.

In MPI the stride is defined to byte stride. But vepu requires 8 pixel
aligned pixel stride.

So we add more code to adapt to both case and check 8 pixel alignment.

From opengles definition:

Stride means bytes in a row of pixels including padding. So an image
could be 510 pixels in width and rounded up to 512 pixels. The stride
would be 512 * bit depth of the image's format. You could also have
stride in pixels in which case the stride would be 512 pixels

Pitch is a little more vague, but typically could be interchangeable
with stride. Considering your reference is specifying in bytes, it's
likely safe to assume they're not measuring in pixels. So the reference
likely means the number of bytes in a row + padding, the only
alternative would be number of bytes without padding e.g. image width *
bit depth.
