libc/common: Add memalign
Memalign is another name for the posix aligned_alloc function, although it
has weaker restrictions on the relationship between the alignment and size.
memalign() is used internally by the libstdc++ when built for 'newlib'
targets (which includes picolibc) instead of aligned_alloc() due to a bug
in gcc, so we need to provide an implementation of this when using that
library, even though it's not part of the Zephyr C library API.
When a fix for the libstdc++ is merged upstream and can be consider a
reasonable dependency for Zephyr, this work-around can be removed.
Closes: #57899
