Docs/mm/damon/design: document DAMON actions when TRANSPARENT_HUGEPAGE is off
MADV_HUGEPAGE and MADV_NOHUGEPAGE are guarded and they are not available
when compiling the kernel without TRANSPARENT_HUGEPAGE option. The DAMON
behaviour is to silently fail [1] in when DAMOS_HUGEPAGE or
DAMOS_NOHUGEPAGE are used, but TRANSPARENT_HUGEPAGE is disabled. Update
the DAMON documentation to reflect this behaviour.
