Use netlink to set MTU in IpClient(1/2)

Currently IpClient uses netd to set MTU for interfaces while the
usage of netd can bring some unexpected side effects and execute in
slower speed.

This change moves forward with one less usage of netd to use netlink
directly set MTU in IpClient.

This patch adds support in netlink utils to set MTU for interfaces.

Bug: 383663804
Test: Manually call and make sure interface MTU is updated
Test: atest NetworkStaticLibTests
