DBENGINE v2 - improvements part 3 (#14269)
* reduce journal v2 shared memory using madvise() - not integrated yet
* working attempt to minimize dbengine shared memory
* never call willneed - let the kernel decide which parts of each file are really needed
* journal files get MADV_RANDOM
* dont call MADV_DONTNEED too frequently
* madvise() is always called with the journal unlocked but referenced
* call madvise() even less frequently
* added chart for monitoring database events
* turn batch mode on under critical conditions
* max size to evict is 1/4 of the max
* fix max size to evict calculation
* use dbengine_page/extent_alloc/free to pages and extents allocations, tracking also the size of these allocations at free time
* fix calculation for batch evictions
* allow main and open cache to have as many evictors as needed
* control inline evictors for each cache; report different levels of cache pressure on every cache evaluation
* more inline evictors for extent cache
* bypass max inline evictors above critical level
* current cache usage has to be taken
* re-arrange items in journafile
* updated docs - work in progress
* more docs work
* more docs work
* Map / unmap journal file
* draw.io diagram for dbengine operations
* updated dbengine diagram
* updated docs
* journal files v2 now get mapped and unmapped as needed
* unmap journal v2 immediately when getting retention
* mmap and munmap do not block queries evaluating journal files v2
* have only one unmap function
