Add initial test and build files for Robolectric unit test suites.

Add initial test and build files for Robolectric unit test suites.

Robolectric allows us to run tests that use Android code in the host
JVM. This means faster and more stable tests since we don't have to
deal with a device. This CL has the build file changes to build the
unit test suite, and two example tests that have been converted to
run with Robolectric.

Converting these before we've got the bots set up to run them means we'll lose
the coverage these tests provide. Can we get the bots set up first, then do the
conversions s.t. the tests move between two targets we're running?

Ok, will commit this CL, then make the bots run the new targets
"content_shell_unit_tests" and "chrome_shell_unit_tests", then delete the
original GamepadMappingsTest and ResponseParserTest.

These values should be (very) small, but nonzero.

Done. Set values to do "ERROR_TOLERANCE = 0.000001f;"

+ nyquist for chrome/android/
+ tedchoc for content/public/android/
+ cjhopman for build files

Added build files and converted 2 tests to Robolectric as examples. After I get
the new content_shell_unit_tests and chrome_shell_unit_tests targets running on
the bots, I plan on deleting the original tests.
