[GraphicsEnvironment] Expose API to query whether an app should use game driver.

Game Driver and ANGLE require to disable graphics driver preloading, which
results in app launch time regression. Given that in early stage, only a few
applications will use them, we would like to make sure Zygote prefork comes
with a preloaded graphics driver, such that applications that don't go through
ANGLE or Game Driver can directly use Zygote prefork without having to load the
driver.

BUG: 130029351
Test: Verify with testing applications.
