Add fallback logic and enable XFRM-I support in netd

This patch adds fallback logic, checking for XFRM-I kernel support, and
switching to use XFRM-I if supported. Fallbacks to VTIs are provided for
backward compatibility with 4.4 kernels. Parameters for VTI versus
XFRM-I are selected based on the kernel support for XFRM interfaces.

This is part of a patch set to enable XFRM-I support, with automatic
fallbacks to VTI in XfrmController (3/3)

Bug: 77856928
Test: Binder tests updated, passing. CTS & unit tests also passing
