Convert cc_test targets with bp2build.

Starting with libutils_test, adb_test, libcutils_test, (and ~47 other host_supported tests).

Test: $ b build --config=android_x86_64 //system/core/libutils:libutils_test && adb push bazel-bin/system/core/libutils/. /data/tmp/libutils_test_files/ && adb shell /data/tmp/libutils_test_files/libutils_test
Test: presubmits with newly converted cc_test targets
Test: $ b test //system/... --config=linux_x86_64 --verbose_failures --test_output=errors --keep_going --build_tests_only

Fixes: 242038415
