Add PRODUCT_MANIFEST_PACKAGE_NAME_OVERRIDES

It is a list of <module_name>:<manifest_name> pairs. When the module
name of an APK or an APEX matches with <module_name>, then its app
manifest name is overridden to <manifest_name>.

<module_name> and <manifest_name> can be patterns as in
com.android.%:com.mycompany.android.%.release

Note that, in case of APEXes, the manifest name refers to the name of
the zip container. The apex manifest name (which is specified in
apex_manifest.json) is not overridden.

Test: m with PRODUCT_MANIFEST_PACKAGE_NAME_OVERRIDES for
1) an APK in Android.mk
2) an APK in ANdroid.bp
3) an APEX
and check that manifest names are modified as specified
