[Merge to M54] TabManager: Set OOM scores via a new debugd interface on ChromeOS.

[Merge to M54] TabManager: Set OOM scores via a new debugd interface on ChromeOS.

Setting OOM scores generally requires root permission. In the past it's done
1. For Chrome processes: via a SUID binary chrome-sandbox.
2. For Andorid processes: Send scores to Android via IPC. Android
handles the rest.

Now a new method is added to debugd dbus interface on ChromeOS to
handle OOM score settings.

So we can set OOM score settings in the unified way on ChromeOS.
