MDEV-21225 Remove ut_align() and use aligned_malloc()

Browse Source 
Before commit 90c52e5291b3ad0935df7da56ec0fcbf530733b4 introduced
aligned_malloc(), InnoDB always used a pattern of over-allocating
memory and invoking ut_align() to guarantee the desired alignment.

It is cleaner to invoke aligned_malloc() and aligned_free() directly.

ut_align(): Remove. In assertions, ut_align_down() can be used instead.
