Use input-vdex-fd, or input-vdex in dex2oat.
input-vdex-fd is used by installd
input-vdex is used by run-tests, and (will be used by) go/lem
This change copies the contents of the passed vdex to the new one,
unquicken the new vdex, and run the fast verification on the new
vdex.
bug:30937355
Test: device boots, apps get updated faster with vdex
Test: set TEST_VDEX to true in run-test-jar, run all tests
Test: 628-vdex
