riscv: Add kprobes KUnit test
...
Add KUnit test for riscv kprobes, mostly for simulated instructions. The
test install kprobes into multiple sample functions, and check that these
functions still return the expected magic value.
This test can detect some kprobe bugs reported in the past (in Link:).

treewide: replace or remove redundant def_bool in Kconfig files
...
'def_bool X' is a shorthand for 'bool' plus 'default X'.
'def_bool' is redundant where 'bool' is already present, so 'def_bool X'
can be replaced with 'default X', or removed if X is 'n'.
