Change default dalvik.vm.jdwp-provider to adbconnection

This changes the default jdwp implementation to be libjdwp with the
connection mediated by libadbconnection.

Test: ./test.py --host -j50
Test: ./art/tools/run-libjdwp-tests.sh --mode=device
Test: Build and run
Test: use ddms monitor.
Test: Use Android Studio.
Test: Build and debug debuggable app (bandhook-kotlin)
Test: Build and debug non-debuggable app on userdebug build
      (bandhook-kotlin)
Test: Debug running system process on userdebug build
      (com.android.packageinstaller)
Test: adb shell stop &&
      adb shell setprop dalvik.vm.jdwp-provider adbconnection &&
      adb shell start;
      Test debugger with explicit adbconnection jdwp provider set
Test: adb shell stop &&
      adb shell setprop dalvik.vm.jdwp-provider default &&
      adb shell start;
      Test debugger with explicit default jdwp provider set
      Ensure debugger is using the 'adbconnection' provider
Test: adb shell stop &&
      adb shell setprop dalvik.vm.jdwp-provider internal &&
      adb shell start;
      Test debugger with explicit internal jdwp provider set
      Ensure debugger is using the old internal jdwp implementation.
