Test bootImageConfig/Variant fields

Most of the fields in the bootImageConfig/Variant structs are assigned
inside a Once func so are guaranteed to be only set once. However, some
are assigned outside. This change adds comprehensive tests for those
structs and verifies that the constant fields are preserved and the
mutated fields have the correct value.

The check for the constant fields is added in a new TestBootImageConfig
test.

The check for the mutated fields is added into
TestSnapshotWithBootclasspathFragment_ImageName as that test checks an
art bootclasspath_fragment in the following configurations:
* source on its own
* prebuilt on its own
* source and prebuilt with source preferred
* source and prebuilt with prebuilt

It reveals a couple of interesting facts:
* All the *installs fields are set to the same value irrespective of
  whether the source or prebuilt is preferred. The information is
  constructed solely from information already within the
  bootImageConfig/Variant and so can be moved within Once.

* The licenseMetadataFile is incorrect when prebuilt is preferred.
  That is due to both the source and prebuilt modules setting it and
  the source module always wins as the source module depends on the
  prebuilt so always runs its GenerateAndroidBuildActions after it.

Those issues will be cleaned up in following changes.
