Roshan Pius 3aa1c1725e sepolicy: Permission changes for new wifi mainline module
Move wifi services out of system_server into a separate APK/process.

Changes:
a) Created sepolicy for the new wifi apk.
b) The new APK will run with network_stack uid (eventually will be moved
to the same process).

Used 'audit2allow' tool to gather list of permissions required.

Note: The existing wifi related permissions in system_server is left
behind to allow the module to be loaded into system_server or
network_stack process depending on device configuration.

Bug: 113174748
Test: Device boots up and able to make wifi connection.
Test: Tested hotspot functionality.
Test: Ran WifiManagerTest & WifiSoftApTest ACTS tests locally.
Test: Will send for wifi regression tests.
