Allow grappling hook to optionally work on all blocks

[BogTheMudWing]

Right now, making a grappling hook uses this boolean in the custom_data component:

/give @p fishing_rod[custom_data={grappling_hook:1b}]

Phen requested we open up the option to allow a grappling hook to work on all blocks. Something like this:

/give @p fishing_rod[custom_data={grappling_hook:{any_blocks:1b}}]

Where the presence of grappling_hook:{} determines if it is a grappling hook, and any_blocks:1b is a boolean where, if true, the grappling hook will work on all blocks. Otherwise (if false or not specified), only target blocks.
