Add a system property to disable odrefresh.

This change adds a system property "dalvik.vm.disable-odrefresh", which
disables odrefresh.

This option can be used for making the boot quicker, for faster
iteration during development. It should never be enabled for production.

Bug: 309011617
Test: Set the property to true and see no dex2oat invoked by odrefresh.
