Move emulator specific configurations to vendor

The moved files are all emulator specific so should reside in vendor
directory/partition. This modification resolves a Launcher crash
issue when GSI boots on the emulator. Directly relevant file is
handheld_core_hardware.xml, which is absent from the GSI.

All other files moved in this change can cause similar issues (if they
stay under /system) since they aren't present on GSI, either.

Bug: 67987112
Test: x86 GSI boots to home screenon with 2 emulator products, aosp_x86,
      and sdk_gphone_x86 on the x86 emulator (on internal master).
      Both aosp_x86 and aosp_x86_64 boot to home screen on the emulator.
      Both aosp_arm and sdk_phone_arm boot to home screen on the arm
      emulator.
