Adopted erase_size config changes in block devices and test runners

Browse Source 
This ended up needing a bit of API rework since littlefs no longer needs
to know the actual erase_count. We can no longer rely on lfs_config to
contain all the information necessary to configure the block devices.

Changing the lfs_bd_config structs to be required is probably a good
idea anyways as it moves us more towards separating the bds from
littlefs, though we can't quite get rid of the lfs_config parameter
because of the block-device API in lfs_config. Eventually it would be
nice to get rid of it, but that would require API breakage.
