Christopher Haster ff84902970 Moved out block device tracing into separate define ...

Block device tracing has a lot of potential uses, of course debugging,
but it can also be used for profiling and externally tracking littlefs's
usage of the block device. However, block device tracing emits a massive
amount of output. So keeping block device tracing on by default limits
the usefulness of the filesystem tracing.

So, instead, I've moved the block device tracing into a separate
LFS_TESTBD_YES_TRACE define which switches on the LFS_TESTBD_TRACE
macro. Note that this means in order to get block device tracing, you
need to define both LFS_YES_TRACE and LFS_TESTBD_YES_TRACE. This is
needed as the LFS_TRACE definition is gated by LFS_YES_TRACE in
lfs_util.h.
