Remove H5B debug checks (#4089)

The H5B (version 1 B-tree) package would add some computationally
expensive integrity checks when H5B_DEBUG was defined. Due to their
negative effects on performance, this option was rarely turned on,
making the H5B__assert() check function stale, if not dead, code.

This change:

* Builds H5B__assert() when NDEBUG is not defined (the function
  relies on assert()) so it gets compiled more often.
* Removes some printf debugging statements in the B-tree code
* Removes all H5B "extra debug" checks that are leftover from
  past debugging sessions. Maintainers can add H5B__assert()
  selectively to perform integrity checks when debugging.
* Removes the HDF5_ENABLE_DEBUG_H5B CMake option

H5B_DEBUG now has no effect
