Implement the output packaging step in the GeneralTestsOptimizer. This
step takes all the outputs built by the general-tests target (in the
case where it was optimized) and packages them into the necessary zips
generated by the target normally.

Implement functionality in GeneralTestsOptimizer to find what targets to
build.
This logic is fairly complex and involves checking for test
configs that download general-tests.zip. Then the configs are checked to
see if they're proper test mapping tests (if they use the
'test-mapping-test-group' option). If they are, then TEST_MAPPING
modules are scanned to see if the list of changed files would cause any
test mapping modules to run. The tests are then further filtered by
test-mapping-test-groups used in the test configs.
In case that a test uses general-tests.zip but does not specify
'test-mapping-test-group' then all bets are off and general-tests.zip
is built in its entirety.
package_outputs is still unimplemented so this will need to be
implemented before the optimization can be enabled.
Test: atest build_test_suites_test && atest optimized_targets_test
