watchdog: pretimeout: Convert dump pretimeout governor to tristate
Commit 645ad41da8b2 ("watchdog: pretimeout: Add "dump" pretimeout
governor") added the "dump" watchdog pretimeout governor, but restricted
it to built-in code because trigger_all_cpu_backtrace() was not exported
to loadable modules.
Now that CPU backtrace APIs are supported for loadable kernel modules
via cpumask_backtrace(), convert WATCHDOG_PRETIMEOUT_GOV_DUMP to
tristate. This allows kernels to deliver the pretimeout governor as a
loadable kernel module.
