[PATCH v3 3/5] dynamic_debug: expose printing declarations with the core enabled

[Zhi Wang]

The dynamic debug printing functions exist whenever DYNAMIC_DEBUG_CORE is
enabled, even if the current translation unit has not opted in to debug
callsites. Expose their declarations under that same condition.

Rust bindings and helpers are compiled independently of the driver crates
that opt in with DYNAMIC_DEBUG_MODULE. They need the declarations in a
CORE-only configuration without enabling callsites globally. Leave the
existing conditions around the callsite macros unchanged.
