Atoms embedded in pids/ports/refs are by default encoded as SMALL_ATOM_UTF8_EXT.
Ports switch to a new format with longer IDs, V4_PORT_EXT. This required adding a prefix byte to signal the longer IDs, but also to ensure their sorting is consistent with the sorting of the previous format.
Tested (only eunit since I don't have EQC) with OTP 24.3.4.14 and 26.1.2.
