edify: Move the testcases to gtest.
Now they live in tests/component/edify_test.cpp.
Also rename edify/main.cpp to edify/edify_parser.cpp. It becomes a
host-side debugging tool that validates the input edify script. However,
it supports edify builtin functions only and doesn't recognize the ones
defined via updater.
Test: recovery_component_test passes on device.
