Make mcl_enchanting use the new mcl_autogroups

The function mcl_autogroups.get_groupcaps is used by mods to get the
groupcaps for tools with efficiency enchantments.  This function is used
by mcl_enchanting when enchanting tools with efficiency.

-- Get the groupcaps for a tool on the specified digging groups. groupcaps_def
-- contains a table with keys being the digging group and values being the tools
-- properties for that digging group.
--
-- The tool properties can have the following values:
--
-- tool_multiplier - the digging speed multiplier for this tool (default 1)
-- efficiency - the efficiency level for this tool (default 0)
-- level - the maximum level of the group the tool can harvest (default 1)
-- uses - the number of uses the tool has for this group
--
-- A level of 0 means that the tool will be able to dig that group but will
-- never be able to harvest the nodes of that group and will always get a
-- digging time penalty. This is useful for implementing the hand.
--
-- Example usage:
--
-- mcl_autogroup.get_groupcaps {
-- pickaxey = { tool_multiplier = 4, level = 3, uses = 132 }
-- }
--
-- This computes the groupcaps for a tool mining "pickaxey" blocks. The tool
-- has a digging speed multiplier of 4, can mine nodes of level >= 3 and has 132
-- uses.
