Common test main

Merge from Widevine repo of http://go/wvgerrit/56521

This CL adds a common main routine for integration tests.  It sets a
default test configuration for the provisioning and license server
urls and certificates, and allows the user to set them on the command
line.

Test: current unit tests still pass.
Bug: 72354901 Fix Generic Crypto tests.
