Migrate VCN to separate non-updatable libraries

This patch migrates VCN framework code from framework-minus-apex
to framework-connectivity-b, and VCN service code to
service-connectivity-b-pre-jarjar. This patch is part of the work
to move VCN to the Tethering module.

Design doc: go/mainline-vcn-eng-design

Bug: 369703242
Test: FrameworksVcnTests, CtsVcnTestCases, CtsStrictJavaPackagesTestCases
Flag: EXEMPT code refactoring; no functional change
