Move the test build command to a script that lives in-source and
intended to be called by the Android CI build system.
This script optimizes the build when change information is available by
only building relevant test modules. More specifically, only 'affected'
test modules listed in Test Mapping configuration files are built.
Using this script is expected to reduce build times and generate a
smaller `general-tests.zip` file which had increased to over 30 GB.
Test: ./build/make/ci/build_test_suites --target_product aosp_x86_64
--target_release trunk_staging --with_dexpreopt_boot_img_and_system_server_only --dist_dir <dist_dir> --change_info <change_info_file> <extra_targets>
