Reimplement third_party/libopenjpeg20/opj_malloc.h.

Reimplement opj_malloc() and related memory (de)allocation functions
used by OpenJPEG. Instead of being based on a bunch of if-defs based on
platforms and compilers, standarize on using PartitionAlloc for normal
allocations, and use third_party/base/memory/aligned_memory.h for all
aligned allocations.

This fixes a mismatch where the previous implementation assumed many
64-bit POSIX platforms allocate 16-byte aligned memory, when OpenJPEG
actually requires 32-byte alignment in some cases.
