Andrey Konovalov 76bc99e81a kasan: fix HW_TAGS boot parameters
The initially proposed KASAN command line parameters are redundant.

This change drops the complex "kasan.mode=off/prod/full" parameter and
adds a simpler kill switch "kasan=off/on" instead.  The new parameter
together with the already existing ones provides a cleaner way to
express the same set of features.

The full set of parameters with this change:

  kasan=off/on             - whether KASAN is enabled
  kasan.fault=report/panic - whether to only print a report or also panic
  kasan.stacktrace=off/on  - whether to collect alloc/free stack traces

Default values:

  kasan=on
  kasan.fault=report
  kasan.stacktrace=on  (if CONFIG_DEBUG_KERNEL=y)
  kasan.stacktrace=off (otherwise)
