Revert "Change default dalvik.vm.jdwp-provider to adbconnection"

If DDMS is being used on a userdebug or eng build it will cause the
libjdwp agent to be loaded on various system processes, most notably
system_server. This will cause a massive performance hit as it tries
to force system_server to jit but, due to security policies, it is
forced to interpreter instead.

Until this can be fixed we are changing the default back to the
internal jdwp provider.

This reverts commit a76605a4.

Bug: 72381923

Bug: 72336488

Test: Boot userdebug with ddms monitor running.

Reason for revert: DDMS forcing system_server to interpreter causing
                   massive perf problems on userdebug builds.
