wifi(vts): Add framework for gtests

These tests don't do much currently other than assert that we can
configure the chip in the required modes and create all the iface
objects.
The |wifi_hidl_test_utils| contains all helper functions that will be
shared across the different test fixtures.

Bug: 33459306
Test: adb root && adb remount && adb push
out/target/product/angler/data/nativetest/wifi_hidl_test/wifi_hidl_test
/data/ && adb shell /data/wifi_hidl_test
