[view compiler] Add test coverage for layouts compiled from APK

The existing LayoutCompilerTest only covered compiled layouts generated from
text XML files. It did not cover layouts that were extracted from the APK. This
is an important area to cover.

This test works by calling `pm compile --compile-layouts` on the test APK, and
then directly loads the `compiled_view.dex` file. From there, it pulls out the
compiled layouts and executes their inflater. This makes sure the generated DEX
files validate and execute without error.
