Add the following devlink port attributes:
PortNumber: the physical port number
PfNumber: the PF number
VfNumber: the VF number (index)
SfNumber: the SF number (index)
ControllerNumber: the controller number
External: if set, indicates external controller

Refactors test setup and teardown logic to use `t.Cleanup` instead
of `defer`. This ensures that cleanup functions are correctly scoped
to each subtest's lifecycle, improving test isolation and reliability.
The `setUpNetlinkTest` helper function is also improved to correctly
save and restore the original network namespace, ensuring that tests
do not leak state.
To support this, a `Close()` method that returns an error is added to
the `Handle` struct, allowing for proper cleanup of underlying netlink
sockets. The test helpers are updated to use this new method,
preventing resource leaks between tests.
Additionally, a bug in the `netns` tests is fixed where a large
namespace ID could overflow a 32-bit integer, causing spurious
failures on some systems.
Functions added:
DevlinkGetDeviceParams - get all parameters for device
DevlinkGetDeviceParamByName - get specific parameter for device
DevlinkSetDeviceParam - set parameter for device

This patch adds very basic support for getting information about
devlink devices which are typically PCI devices which exposes Networking
switch or legacy devices.
This information includes bus name, device name and eswitch modes.
This is done through devlink family of commands via generic netlink
sockets provided by Linux kernel.
DevlinkDevice represents a devlink device which is identified by bus
name and device name (unlike interface index for netdevices).
It contains the DevlinkDevAttrs device attributes.
Currently only eswitch attributes are queried. In future more attributes
such as port, shared buffer, traffic class will be added.
