RESTRICT AUTOMERGE: O Backport: Add a regression test for bug 118835133

Adding a basic test to ensure we don't the same issue in
future.

Bug: 118835133
Test: run cts-dev -m CtsTextTestCases -t android.text.format.cts.TimeTest

Backport notes:

The TimeTest.test_bug118835133 regression test is being backported here to
still-supported CTS releases to alert partners to problems they will
experience if they take the "tzdata" file from releases after Q/10 and use
them with source trees for releases before Q.

If the TimeTest.test_bug118835133 test fails you have a problem that
will affect time zone calculations in some zones (e.g. Asia/Singapore
and Europe/Istanbul). These problems have been fixed on latest code
but there are no plans to backport them.

Do NOT use files from one release with another: releases before Q have
compatibility issues with tzdata files produced using zic versions > 2014b.
Android upgraded to a newer zic version after Q. The ICU files have to
be updated at the same time and .dat files from one Android release
won't work with a different release.

At the time of writing, the Android team provide backports for O-MR1
and P releases and place them in the associated aosp/XXX-dev branch. Reach out
to your partner contact for more information. For those without a partner
contact, look for topics in the AOSP gerrit that changed system/timezone
and external/icu after the release tag. Apply ALL of the incremental changes in
order. Partners with changes to ICU data will find the changes won't
apply cleanly due to the .dat binary files contained in the commits. Apply
the changes to source files and then regenerate the binary files using
system/timezone/update-tzdata.py.

The Android team do not currenly provide backports for release before
O-MR1.
