don't create SDK variants.  Also clear the sdk_version property
for modules that don't have SDK variants so that later code doesn't
use it to trigger SDK behaviors.

Implement bp2build codegen as a discrete step that runs after an
alternatively registered pipeline of mutators, instead of a
presingleton.

bp2build codegen requires a Context that supports VisitAllModules and
PathContext, so this CL also makes a BpToBuildWrapperContext that
conforms to PathContext by adding two method implementations.

Dexpreopt and boot jars package check all require access to dex
implementation jars created for java_library and java_sdk_library. They
were available when building from source but not when building from
prebuilts, even though they are embedded within the .apex files that
are referenced from prebuilt_apex.

This changes adds support to prebuilt_apex to export the dex
implementation jars and updates java_import to use those exported dex
implementation jars.

In a source build dexpreopt/boot jars package check access the apex (or
platform) specific variant of a java_library, e.g. core-oj, from which
it retrieves the dex implementation jar path.

After this change in a prebuilt build dexpreopt/boot jars package check
behave in the same way except in this case they retrieve the dex
implementation jar path from the apex (or platform) specific variant of
the java_import, e.g. core-oj.

The work to export files from a `.apex` file for use by other modules
is performed by a new `deapexer` module type. It is not used directly
in an `Android.bp` file but instead is created implicitly by
`prebuilt_apex`,

In order to do that this contains the following changes:
* Adds a new `dexapexer` module type to handle the exporting of files
  from the `.apex` file.
* Adds an exported_java_libs property to prebuilt_apex to specify the
  set of libraries whose dex implementation jars need exporting.
* Creates apex specific variants of the libraries listed in the
  exported_java_libs property.
* Adds the set of exported files to the ApexInfo to make them available
  to the apex specific variants.
* Prevents the prebuilt_apex variants from being merged together as
  they will not be compatible.
* Modifies java_import to use the exported file for variants of a
  prebuilt_apex.
* Adds a ninja rule to unpack (using deapexer) the contents of the
  prebuilt_apex's apex file, verify that the required files are present
  and make them available as outputs for other rules to use.
* Some minor refactorings to support these changes.
* Adds tests to cover prebuilt only, prebuilt with source preferred,
  and prebuilt preferred with source.

The build has some implicit dependencies (via the boot jars
configuration) on a number of modules, e.g. core-oj, apache-xml, that
are part of the java boot class path and which are provided by mainline
modules (e.g. art, conscrypt, runtime-i18n) but which are not otherwise
used outside those mainline modules.

As they are not needed outside the mainline modules adding them to
the sdk/module-exports as either java_libs, or java_header_libs would
end up exporting more information than was strictly necessary. This
change adds the java_boot_libs property to allow those modules to be
exported as part of the sdk/module_exports without exposing any
unnecessary information.

Some points to note:
* The java_import has to have a valid file for the src property
  otherwise it will be disabled.
* The src property is supposed to reference a jar file but the
  java_boot_libs property will make it reference an empty file (not
  an empty jar) so that any attempt to use that file as a jar, e.g.
  compiling against it, will cause a build failure.
* The name of the file passed to the src property should make it
  clear that the file is not intended to be used.
* The test makes sure that only the jar file is copied to the
  snapshot.
