fixes #5701 The assert half correct, half over-active. When the manager's mutex is held it is okay to transition an existing locktree's reference count from 0 to 1. If the lock isn't held, it's a race, since one thread could be destroying the zero-ref count locktree when you're incrementing the count. The failure occurred with the manager's mutx held (so the assert was overactive) and it's a layering-pain to assert that the manager's mutex is held otherwise, so just get rid of it.

fixes #5351 fixes #5528 merge the new locktree to main. the locktree, locktree manager, and blocking lock request api are implemented at the toplevel under locktree/ and the ydb layer has been modified to use the new API. some kruft has been deleted from various parts of the source tree and these merge also includes a change where we kill 'includes.h'
