Add sqlite3 changes APIs

Bug: 289226544

Add support for sqlite3_changes64() and sqlite3_total_changes64().
The APIs will be made public in a later commit.

Unit tests have been added for the APIs.  The unit tests are
incorporated into the unit test for getLastInsertRowid(), and the
entire test has been moved from SQLiteRawStatementTest to
SQLiteDatabaseTest.

As a code clean-up, the pipeline of "lastInsertRowId()" methods have
been renamed to "getLastInsertRowId()", to match the API council's
decision on the public API.

Test: atest
 * FrameworksCoreTests:android.database.sqlite
