Revert "Revert "Migrate Collator classes to use ICU4J.""
The SDK build is now fixed by adding icu4j as a dependency of docs.
This reverts commit 5fc822e7ef47448adccd73ca2ebbd28a068f5136.

Migrate Collator classes to use ICU4J.
The following benchmarks have been run and show the performance
gains from calling ICU4J.
----- ICU4J -----
benchmark us linear runtime
CollatorIdentical 6.90 ==============================
CollatorPrimary 3.20 =============
CollatorSecondary 3.79 ================
CollatorTertiary 4.28 ==================
vm: app_process
----- ICU4C -----
benchmark us linear runtime
CollatorIdentical 11.75 ==============================
CollatorPrimary 10.01 =========================
CollatorSecondary 9.88 =========================
CollatorTertiary 10.26 ==========================
vm: app_process
All tests relating to Collation pass after this change.
With respect to CJK character loading time, tests were done on a
Nexus 6 running this change, in the US locale and TRADITIONAL_CHINESE
locale.
In EN-US:
Time to load Traditional Chinese collator after boot: 76ms, 76ms
Time to load again: (39ms, 36ms, 36ms), (36ms, 36ms, 48ms)
In ZH-TW:
Time to load Traditional Chinese collator after boot: 37ms, 36ms
Time to load again: (36ms, 36ms, 36ms), (35ms, 37ms, 35ms)
This seems to indicate the system is creating a Collator on boot meaning
that ICU is caching it after the first creation. So if a device is in the
Traditional Chinese locale, the cost of creating Traditional Chinese
collators should have been absorbed at boot time.
Loading up the CJK ideographs uses up around ~500k of memory. From the
above findings, if the device is in a language requiring those characters
then they should be loaded up on boot in the Zygote, which may mean the
memory is shared across processes wishing to use the data.

Update collation tests for icu4c 53.
As of ICU 53, rule strings must begin with a reset '&'.
http://www.unicode.org/reports/tr35/tr35-35/tr35-collation.html#Rules
Also, fewer collation elements exist in ICU 53 because ae-ligature maps to
two rather than three logical collation elements. Now the last one
yields only one CollationElementIterator value rather than two.
Finally, it's no longer possible to switch from forward to backward iteration
without calling reset/setOffset/setText. This used to be undefined behavior
but is now checked.

Fix the default decomposition mode of Collators.
It's unclear why we thought it shouldn't be NO_DECOMPOSITION. That's the
default for both ICU and the RI. This patch undoes the part of the change that
introduced this discrepancy, and undoes a change we made to silence a test
that was warning us about the discrepancy.

Moving tests to be under the libcore.* package.
This is indended to make it easier to run on VMs that restrict the packages
from which application classes can be loaded. For example, on the RI you need
to use the bootclasspath to load these tests.
