Ivan Kobzarev 701e05dcbb Buck test targets robolectric,instrumentattion
Summary:
Buck targets for robolectric and instrumentation tests for pytorch android:
```
buck test fbsource//fbandroid/mode/server //xplat/caffe2/android:test_host
```
```
buck test //xplat/caffe2/android:test_instrumentation
```
For both:
```
buck test fbsource//fbandroid/mode/server //xplat/caffe2/android:pytorch
```

Models in assets:
`pt_android_test_asset` - creates buck target that can be included in both robolectric and instrumentation tests that contains asset created from provided torchscript sources as separate file, using the latest binaries of libtorch.

`pt_gen_test_asset_bin`  does that tacing, usage format
```
generate_test_asset input_file.jit output_file.py
```

Example of test-host setup for users of pytorch android:
robolectric tests:

```
load("fbsource//xplat/caffe2:pt_defs.bzl", "pt_android_test_asset", "pt_predictor_binary", "PT_ANDRIOID_TEST_HOST_JNI_DEPS")

pt_android_test_asset(
    name = "test_asset",
    src = "test_asset.jit",
    asset_name = "test_asset.pt",
)

robolectric3_test(
    name = "example_test_host",
    srcs = [...],
    jni_deps = PT_ANDRIOID_TEST_HOST_JNI_DEPS,
    deps = [
        ":pytorch_common",
        ":test_asset",
        "//fbandroid/java/com/facebook/soloader/annotation:annotation",
        "//fbandroid/java/com/facebook/testing/robolectric/v3:v3",
        "//fbandroid/libraries/soloader/java/com/facebook/soloader:soloader",
        "//fbandroid/third-party/java/robolectric3/robolectric:robolectric",
    ],
)
```
