dumpstate: Collect PCIe link stats [DO NOT MERGE]

Browse Source 
Collect PCIe link statistics in dumpstate.

DO NOT MERGE because the same functionality is already
implemented in dump_pcie.sh in upstream branches.

Test: adb bugreport && unzip bugreport*.zip &&
      grep link_stats dumpstate_board.txt
Bug: 266561593
