This relands commit e7481c5056.
Which was reverted in commit dc8e02663b.
There was an issue in the original CL where the argument
--test_policy_to_pref_mappings_filter gets popuplated when there are no
policy pref mapping test files. This wasn't noticed because c++ unit
tests and browser tests ignore this flag and work correctly. Android
tests OTOH throw an error because the flag is unknown.
This CL filters policy pref mapping files when building the flag.
Original change's description:
> autotest.py: Support policy to pref mappings tests
>
> Pref mapping test files now work, for example:
> $ tools/autotest.py -C out/Default \
> components/policy/test/data/pref_mapping/NewWindowsInKioskAllowed.json
> $ tools/autotest.py -C out/Default \
> components/policy/test/data/pref_mapping \
> --test_policy_to_pref_mappings_filter=NewWindowsInKioskAllowed
>
> Which are equivalent to:
> $ autoninja -C out/Default browser_tests
> $ out/Default/browser_tests \
> --gtest_filter="*PolicyPrefsTest.PolicyToPrefsMapping" \
> --test_policy_to_pref_mappings_filter="NewWindowsInKioskAllowed"
>
