MDEV-24142: Remove the LatchDebug interface to rw-locks
The latching order checks for rw-locks have not caught many bugs
in the past few years and they are greatly complicating the code.
Last time the debug checks were useful was in
commit 59caf2c3c1fe128d1d2c3a8df9fadd4d25ab7102 (MDEV-13485).
The B-tree hang MDEV-14637 was not caught by LatchDebug,
because the granularity of the checks is not sufficient
to distinguish the levels of non-leaf B-tree pages.
The interface was already made dead code by the grandparent
commit 03ca6495df31313c96e38834b9a235245e2ae2a8.
