bugs/core: Introduce the CONFIG_DEBUG_BUGVERBOSE_DETAILED Kconfig switch
Allow configurability of the inclusion of more detailed
WARN_ON() strings, to be implemented in subsequent
commits.
Since the full cost will be around 100K more memory on
an x86 defconfig, disable it by default.
Provide the WARN_CONDITION_STR() macro to allow the conditional
passing of extra strings to lower level BUG/WARN handlers.
