[RFC PATCH 2/2] mm/damon/Kconfig: enable CONFIG_DAMON by default

[SeongJae Park <sj@kernel.org>]

As of this writing, a few major distros including Alma, Amazon, Android,
CentOS, Debian, Fedora, and Oracle are build-enabling DAMON (set
CONFIG_DAMON[1]).  Enabling it by default will help configuration setups
for them and future users easier.

Build-enabling DAMON does not introduce a real risk since it makes no
behavioral change by default.  It requires users to make explicit
requests to do something.  Only one potential risk is making the size of
the kernel a little bit larger.  On a configuration, it increases the
resulting kernel package size by 337,685 bytes, which is about 0.1 % of
the final package file.

Hence, the benefit of enabling CONFIG_DAMON outweighs the potential
risk.  Set CONFIG_DAMON by default.
