dice: add trusty build rules

Adds the ability to build libdiced_open_dice with the trusty build
system. Besides the various rules.mk files this requires a few changes
to the library itself:

Bindgen changes:

1. The bindgen headers have each been moved to to their own subdir. This
   stems from a limitation in the trusty build system whereby you can't
   have two rules.mk files in the same directory.

2. A lib.rs has been added for each bindgen target. This remains unused
   in the android build, but is needed in the trusty build so we can
   include!() the generated bindings.

Test changes:

1. The tests have been wrapped in a module so that they can be
   conditionally compiled. The trusty build system doesn't support
   building rust test targets on their own. It will attempt to compile
   this code as a non-test target.

2. A feature, `trusty`, has been added to the test crate to guard
   invoking the trusty test harness initialization macro.
