sched/walt: allow reference to walt debug capabilities

Browse Source 
Debug capabilities are needed throughout walt files, while
the walt-specific debug/dumping capabilities are strictly in
walt.c and dependent upon local variables.

Support the ability to cause a crash across all walt functionality.
