Dumpstate: Improve IPC logging on Pixel 2

Browse Source 
Dumpstate on the Pixel 2 currently does not output all of the IPC logs,
which are needed to debug some kernel wakelock issues.

dumpstate_board.txt will now contain the following new sections:
* ipc-servers - contains the contents of /d/msm_ipc_router/dump_servers
* ipc-logs - contains the contents of /d/ipc_logging/*_IPCRTR/log

Bug: 121033207
Test: Ran "adb bugreport" and visually inspected dumpstate_board.txt
