Break grapheme clusters after viramas if they end a cluster
Previously, we stayed on the conservative side and disallowed any
grapheme breaks (and thus cursoring) where a virama was followed by a
letter, since we did not know if the virama would be forming a
cluster with the letter or not. This created problems with Indic
languages with infrequent conjuncts, such as Tamil.
Now we use the information in calculated advances to find if a
cluster is formed. If there is no cluster, we break the grapheme and
allow cursoring after the virama.
Test: Unit tests added to GraphemeBreakTests and MeasurementTests.
Test: Also manually tested Tamil sequences.

Always use minikin namespace.
Here is a new policy of the namespace of minikin.
- All components should be in minikin namespace.
- All tests are also in minikin namespace and no anonymous namespace.

Implement grapheme cluster breaking
This patch includes an implementation of grapheme cluster breaking,
which is especially useful for repositioning the cursor for left and
right arrow key presses. The implementation is closely based on Unicode
TR29, and uses the ICU grapheme cluster break property, but is tailored
to more closely match the existing implementation and expected behavior.
Part of a fix for b/15653110 Improve behavior of arrow keys in EditText
