The goal of this is to keep track of what app processes
are doing, to determine who is being abusive, when the system
is getting into memory constrained situations, and help the
user determine how to resolve this.
Right now it doesn't really do any of that, just keeps track
of how long every process has been running since boot.
Also update the activity manager to use "cached" as the terminology
for what it used to interchangeably call hidden and background
processes, and switch ProcessMap over to using ArrayMap.

When granting a Uri permission with new PERSIST_GRANT_URI_PERMISSION
flag, persist that grant across device reboots until explicitly
revoked. Adds new persistedModeFlags dimension to UriPermission,
and moves all flag mutation into UriPermission for clarity. Adds
flag documentation. Only inflate HashSet as needed.
Write persisted grants into XML file, saving based on source and
target package name and user handle. Sanity check grants when
parsing.
Wipe all grants from/to a package when uninstalled, and wipe any
transient grants when a package or user is force stopped.
Persistable grants are always considered "needed."
