Allow stubs implementation to be omitted
When defining a stubs library, allow specifying that the
implementation library does not need to be installed. This allows for
cases where the implementation is deployed in some non-standard way -
e.g. inside a Microdroid virtual machine.
Without this, we get build errors like: "TARGET module
com.android.compos requires non-existent TARGET module: libvm_payload".
Default behavior is unchanged. The change is protected by an allowlist
to limit usage to the immediate use case.
Bug: 243512108
Test: builds; soong tests pass
Test: Remove allowlist, see build failure
