Now that the android wifi framework has fully switched over to HIDL,
remove the sepolicy permissions for accessing wpa_supplicant using
socket control interface.

While there, also removed the redundant |hwbinder_use|.

Bug: 35707797
Test: Device boots up and able to connect to wifi networks.
Test: Wifi integration tests passed.

Prevent app domains (processes spawned by zygote) from acquiring
locks on files in /system. In particular, /system/etc/xtables.lock
must never be lockable by applications, as it will block future
iptables commands from running.

Test: device boots and no obvious problems.

This is a follow-up to 93391686
which added both
hal_client_domain(cameraserver, hal_graphics_allocator) and
binder_call(cameraserver, hal_graphics_allocator). The latter
binder_call rule is no longer needed because it is automatically
granted by virtue of cameraserver being marked as a client of
Graphics Allocator HAL --

HALs are intended to be limited responsibility and thus limited
permission. In order to enforce this, place limitations on:
1. What processes may transition into a HAL - currently only init
2. What methods may be used to transition into a HAL - no using
   seclabel
3. When HALs exec - only allow exec with a domain transition.

Test: Build aosp_marlin, aosp_bullhead, aosp_dragon. Neverallow rules
      are compile time assertions, so building is a sufficient test.

Apps should be able to access the configstore HAL since framework
libraries which are loaded into app process can call configstore.

Letting apps have direct access to this HAL is OK because: 

(1) the API of this HAL does not make clients provide any sensitive 
information to the HAL, which makes it impossible for the HAL to 
disclose sensitive information of its clients when the HAL is 
compromised, 

(2) we will require that this HAL is binderized (i.e., does not run 
inside the process of its clients), 

(3) we will require that this HAL runs in a tight seccomp sandbox 
(this HAL doesn't need much access, if at all) and,

(4) we'll restrict the HALs powers via neverallows.

Test: apps can use configstore hal.

This switches Allocator HAL policy to the design which enables us to
identify all SELinux domains which host HALs and all domains which are
clients of HALs.

Allocator HAL is special in the sense that it's assumed to be always
binderized. As a result, rules in Camera HAL target hal_allocator_server
rather than hal_allocator (which would be the server and any client, if
the Allocator HAL runs in passthrough mode).

Every client of Graphics Allocator HAL needs permission to (Hw)Binder
IPC into the HAL.

Test: Device boots, no denials to do with hal_graphics_allocator
      (also, removing the binder_call(hal_graphics_allocator_client,
      hal_graphics_allocator_server) leads to denials)

This switches Boot Control HAL policy to the design which enables us
to conditionally remove unnecessary rules from domains which are
clients of Boot Control HAL.

Domains which are clients of Boot Control HAL, such as update_server,
are granted rules targeting hal_bootctl only when the Boot Control HAL
runs in passthrough mode (i.e., inside the client's process). When the
HAL runs in binderized mode (i.e., in another process/domain, with
clients talking to the HAL over HwBinder IPC), rules targeting
hal_bootctl are not granted to client domains.

Domains which offer a binderized implementation of Boot Control HAL,
such as hal_bootctl_default domain, are always granted rules targeting
hal_bootctl.

P. S. This commit removes direct access to Boot Control HAL from
system_server because system_server is not a client of this HAL. This
commit also removes bootctrl_block_device type which is no longer
used. Finally, boot_control_hal attribute is removed because it is now
covered by the hal_bootctl attribute.
