This patchset adds a stress test for kprobes and a test for checking
optimized probes.
The two tests are being added based on the below discussion:

https://lore.kernel.org/all/1682506809.uus6y0ir3i.naveen@linux.ibm.com/#t
Changelog:
v3:
* Add Acked-by for kprobe_insn_boundary.tc
* Simplify test for optimized probe, as suggested by Masami
* Add exit_unresolved to exit as unresolved in case no probe was optimized
v2:
* Add an explicit fork after enabling the events ( echo "forked" )
* Remove the extended test from multiple_kprobe_types.tc which adds
multiple consecutive probes in a function and add it as a
separate test case.
* Add new test case which checks for optimized probes.

In the end of the test, there will be an error message induced by the
`ip netns del ns1` command in cleanup()
Tests passed: 201
Tests failed: 0
Cannot remove namespace file "/run/netns/ns1": No such file or directory
Redirect the error message to /dev/null to mute it.
