Replace framework.jar with framework-minus-apex.jar

framework.jar is now a build-time only library which has private symbols
from framework-minus-apex.jar and public symbols from APEXes. Instead of
framework.jar, framework-minus-apex.jar is installed to the device.

framework-minus-apex is installed as framework.jar because the name is
pretty widespread throughout Android. Keeping the original file name for
the backwards compatibility.

Bug: 139391334
Test: m, inspect the build system.img and check that
system/framework/framework.jar exists
