Add framework-virtualization to combined_apis

Since framework-virtualization is part of a non-updatable APEX module,
it should still be allowed to compile against unstable APIs. However,
the current setup of all-framework-module-impl prevents that, since the
all-framework-module-lib target compiles against module_sdk.

This change works around this by introducing the
updatable-framework-module-impl target which builds against
module_current SDK, and includes all updatable modules.

The non-updatable modules are then statically linked into the
all-framework-module-impl target, which builds against hidden APIs.
