erts: Convert small sub-binaries to heap-binaries
In many cases sub-binaries costs more memory than converting them to heap-binaries.
Sub-binaries also has a hidden cost of pinning larger binaries in memory.
By converting binaries this cost is reduced.
Byte aligned sub-binaries upto 24 bytes (64-bit) or 12 bytes (32-bit) are converted.
