selftest: netcons: add test for netconsole over bonded interfaces
This patch adds a selftest that verifies netconsole functionality
over bonded network interfaces using netdevsim. It sets up two bonded
interfaces acting as transmit (TX) and receive (RX) ends, placed in
separate network namespaces. The test sends kernel log messages and
verifies that they are properly received on the bonded RX interfaces
with both IPv4 and IPv6, and using basic and extended netconsole
formats.
This patchset aims to test a long-standing netpoll subsystem where
netpoll has multiple users. (in this case netconsole and bonding). A
similar selftest has been discussed in [1] and [2].
This test also tries to enable bonding and netpoll in different order,
just to guarantee that all the possibilities are exercised.

selftests: net: add netconsole test for cmdline configuration
Add a new selftest to verify netconsole module loading with command
line arguments. This test exercises the init_netconsole() path and
validates proper parsing of the netconsole= parameter format.
The test:
- Loads netconsole module with cmdline configuration instead of
dynamic reconfiguration
- Validates message transmission through the configured target
- Adds helper functions for cmdline string generation and module
validation
This complements existing netconsole selftests by covering the
module initialization code path that processes boot-time parameters.
This test is useful to test issues like the one described in [1].

selftests: netconsole: Add support for basic netconsole target format
Extend the netconsole selftest to validate both basic and extended
target formats. The basic format is a simpler variant that doesn't
support userdata or release functionality.
The test now validates that netconsole works correctly in both
configurations, improving test coverage for different netconsole
deployment scenarios.

netconsole: selftest: Delete all userdata keys
Modify the cleanup function to remove all userdata keys created during the
test, instead of just deleting a single predefined key. This ensures a
more thorough cleanup of temporary resources.
Move the KEY_PATH variable definition inside the set_user_data function
to reduce global variables and improve encapsulation. The KEY_PATH
variable is now dynamically created when setting user data.
This change has no effect on the current test, while improving an
upcoming test that would create several userdata entries.
