This CL adds the SELinux permissions required to execute
atrace and get userspace tracing events from system services.
This is to enable tracing of events coming from surfaceflinger,
audio HAL, etc.
atrace, when executed, sets a bunch of debug.atrace. properties
and sends an IPC via binder/hwbinder to tell the services to
reload that property.

This CL does NOT affect systrace. In that case (i.e. when
atrace is executed from adb/shell) atrace still runs in
the shell domain and none of those changes apply.

Bug: b/73340039

To better record the network traffic stats for each network interface.
We use xt_bpf netfilter module to do the iface stats accounting instead
of the cgroup bpf filter we currently use for per uid stats accounting.
The xt_bpf module will take pinned eBPF program as iptables rule and run
the program when packet pass through the netfilter hook. To setup the
iptables rules. netd need to be able to access bpf filesystem and run the
bpf program at boot time. The program used will still be created and
pinned by the bpfloader process.

Test: With selinux enforced, run "iptables -L -t raw" should show the
xt_bpf related rule present in bw_raw_PREROUTING chain.

This change adds the support of odm sepolicy customization, which can
be configured through the newly added build varaible:
    - BOARD_ODM_SEPOLICY_DIRS += device/${ODM_NAME}/${BOM_NAME}/sepolicy

Also moving precompiled sepolicy to /odm when BOARD_ODM_SEPOLICY_DIRS
is set. On a DUT, precompiled sepolicy on /odm will override the one in
/vendor. This is intentional because /odm is the hardware customization
for /vendor and both should be updated together if desired.

Allow init the ability to relabel recovery block devices. In the case
where we have recovery as a chain partition, due to its presence in
early mount node, init, in first stage itself would require relabel
permissions for the restorecon operation on recovery block device.
