Subject: [PATCH] Query to SystemProperties for BLAST Flag

For some reason DeviceConfig is not successfully querying the
value on crosshatch - move to query SystemProperties directly

Bug: 147096935
Test: build, boot, adb shell device_config put
window_manager_native_boot wm_use_blast_adapter true/false + reboot
