sema: add comptime_int → bool coercion in semaCoerce

When coercing comptime_int to bool, produce the correct bool constant
(IP_INDEX_BOOL_TRUE/FALSE) instead of trying to create an IP_KEY_INT
entry with bool type (which wouldn't match the pre-interned bool constants).

Ported from Sema.zig coerce comptime_int → bool path.
