Trace consumers still read PLIO names by logical channel slot, so nonzero stream IDs can remain "unused".

Address review on Xilinx#125: PLIO names were stored in mm2s_names/s2mm_names by stream ID but read back by channel slot, so only stream 0 worked. Restore GMIO-only population in getInterfaceTiles, look up PLIO names from port_names[streamPortId] in configStreamSwitchPorts, and stop edge aie_trace.cpp from overwriting PLIO names.

Address Copilot review: the VE2 zocl interface-tile path overwrote PLIO mm2s/s2mm names set by configStreamSwitchPorts with "unused". Only set these names for GMIO, matching the edge plugin. Co-authored-by: Cursor <cursoragent@cursor.com>

Populate mm2s_names/s2mm_names for PLIO interface tiles (indexed by stream ID), so SelTraceConfig in aie_event_runtime_config carries the real port names instead of "unused" and hwanalyze stops falling back to default port names for mm2s_ports/s2mm_ports trace.
Tested on aie1 (vck190) with (tile_based_interface_tile_metrics=all:mm2s_ports) in xrt.ini . Diffing aie_event_runtime_config_0.json before and after the fix, the only changes are the four traced interface tiles (22,0), (23,0), (26,0) and (28,0): mm2s_names[0] went from "unused" to G.in[2], G.in[1], G.in[0] and G.in[3]. Each name matches the input PLIO for that column in the design's aie_control_config.json. All other entries, including the AIE-tile all_stalls blocks, were unchanged.
