ShapeDetection: add UseCounter for TextDetector.detect() calls

Because is being used as the popularity of [1] bears witness to, and
we'd like to measure it.

Shape detection: moar content_browsertests (face, qr/barcode)

In the spirit of "if it can be tested, it ought to be tested", this
CL cleans up and expands the a few tests related to Shape Detection.

- the current content_browsertest, which on ToT is extended to
work on Mac and cleaned up (generalized and parameterized, variable
names clarified).

- the test face is changed to a smaller, public domain one of size
6182B (~1.4K smaller).

- Also corrected names: s/shapedetection/shape_detection/

- QR/barcode and text detection in Android is based on coreGMS,
so need to be tested under chrome/. A new ShapeDetectionTest.java
is added for that.  To use coreGMS, we have to guarantee that
StrictMode.allowThreadDiskWrites().

With the tests in #6 in place, I think we're good here.
