Do not include unnecessary tool_capabilities

This commit makes enchanted tools which have no use for
tool_capabilities to not include it in their metadata.  It does this by
not including tool_capabilities in the metadata of an enchanted tool if
at least one of two cases is true:

(1) The tool is not enchanted with unbreaking or efficiency
(2) The tool does not have tool_capabilities defined in its definition

The first case covers situations like having a pickaxe only being
enchanted with silk_touch.  The second case covers situations like a
piece of armor being enchanted with unbreaking.
