lockdep: Introduce lock_acquire_exclusive()/shared() helper macros
In lockdep.h, the spinlock/mutex/rwsem/rwlock/lock_map acquire macros have different definitions based on the value of CONFIG_PROVE_LOCKING. We have separate ifdefs for each of these definitions, which seems redundant. Introduce lock_acquire_{exclusive,shared,shared_recursive} helpers which will have different definitions based on CONFIG_PROVE_LOCKING. Then all other helper macros can be defined based on the above ones, which reduces the amount of ifdefined code.
