hal_wifi: Allow wifi hal to access LOWI server

HAL wifi creates a LOWI client for accessing the LOWI server to share
wifi gscan results for location purposes.
Move all "location" access permissions from system_server to hal_wifi
since these were most likely added for the old wifi hal which was loaded
in system_server.

Bug: 35959128
Test: Device boots up and able to connect to wifi network.
Denials no longer seen. Previously some wifi HAL calls would take
a long time to complete because it tries to create a LOWI client for
every request and fail.
