locking/refcounts: Include fewer headers in <linux/refcount.h>
Debloat <linux/refcount.h>'s dependencies:
- <linux/kernel.h> is not needed, but <linux/compiler.h> is.
- <linux/mutex.h> is not needed, only a forward declaration of "struct mutex".
- <linux/spinlock.h> is not needed, <linux/spinlock_types.h> is enough.
