Avoid integer overflows in align_image_dimension()

Impose maximum values on the input parameters so that we can perform
arithmetic operations without worrying about overflows.

Fix a bug (introduced in commit 7aa2edc) that the ~ operator is applied
to (stride_align - 1), which is unsigned int, and then the result is
converted to uint64_t.

Also change the AomImageTest.AomImgAllocHugeWidth test to write to the
first and last samples in the first row of the Y plane, so that the test
will crash if there is unsigned integer overflow in the calculation of
stride_in_bytes.
