driver core: add TAINT_FORCED_BIND for when userspace manually messes with 
devices and drivers

This commit adds a new taint flag, TAINT_FORCED_BIND, which is set whenever
userspace binds or unbinds a driver via sysfs. This helps developers identify
when fuzzing tools or userspace have forcefully reassigned devices.

[Severity: Low]
Does this call break the build when CONFIG_MODULES is disabled?

Looking at the fallback stub in include/linux/module.h for !CONFIG_MODULES,
there is a syntax error in the parameter list (an extra comma instead of a
space):

static inline void add_taint_module(struct module *mod, unsigned flag,
                                    enum lockdep_ok, lockdep_ok)
{
        add_taint(flag, lockdep_ok);
}

Using add_taint_module() here exposes this syntax error, which causes a hard
build failure when compiling without module support.
