Migrate options in TEST_MAPPING -> Android.bp

This is the first of several cls to start the migration of options in
TEST_MAPPING files to being specified in Android.bp files.

The overall goal is to get local (atest) runs closer to CI runs of the
tests.

These all have FrameworksServicesTests as the base test and all
TEST_MAPPING files to refer to these new test modules reside under this
(servictests) directory.

Step 1) Introduce new modules and list them in TEST_MAPPING postsubmit
Step 2) Wait a week for SLO checker to accept the new modules.
Step 3) Replace current presubmit TEST_MAPPING entries with the module
names.
This second CL will be part of the same topic, which will also run in
presubmit ...

Later steps will ensure that if new options are added to these
TEST_MAPPING files, they will get converted too, but nothing is
preventing that yet.

This was hand-crafted cl, not using the migration script yet.
I am starting with one directory that has several TEST_MAPPING files
below and converting them all, thus 10 new modules instead of 1 or 2.

For these tests, the out dir increases by 1.7 Gig (total for all them).

Ran atest and verified the test that ran matched the new filters.
Test: atest --test-mapping src/com/android/server/contentcapture:postsubmit
Test: atest --test-mapping src/com/android/server/contentprotection:postsubmit
Test: atest --test-mapping src/com/android/server/location/contexthub:postsubmit
Test: atest --test-mapping src/com/android/server/om:postsubmit
Test: atest --test-mapping src/com/android/server/os:postsubmit
Test: atest --test-mapping src/com/android/server/pm:postsubmit
    # 4 postsubmit tests fail, but there were already failing
Test: atest --test-mapping src/com/android/server/recoverysystem:postsubmit
