bufmgr: fewer calls to BufferDescriptorGetContentLock
We're planning to merge buffer content locks into BufferDesc.state. To reduce
the size of that patch, centralize calls to BufferDescriptorGetContentLock().
The biggest part of the change is in assertions, by introducing
BufferIsLockedByMe[InMode]() (and removing BufferIsExclusiveLocked()). This
seems like an improvement even without aforementioned plans.
Additionally replace some direct calls to LWLockAcquire() with calls to
LockBuffer().
