Changes

Cleanup tool tanks taking advantage of tool stats and modifier traits

Instead of shuffling the owner with every modifier implementing tanks, we have a single modifier that implements the tank, and other modifiers just add it as a trait
Modifiers using tanks can use the new helper to get and modify the fluid, instead of needing to talk to the module directly
Tank capacity has been moved from a volatile integer to a tool stat, reducing the need to have specialized modules for it. Custom tanks will just want to add their own custom stats or can handle capacity in another way if they prefer
Repackaged a few capability stuff as part of this commit
This refactor notably fixes fluid overflowing when tank capacity changes (#5190)

Fix misplaced character in tool book page

Call modifier removal hook on modifier traits

Remove mud bricks in favor of the vanilla block

The casting recipe now produces mud (water bottle + dirt is a vanilla recipe)
Still considering if there is a good way to get muddy mangrove roots or packed mud with the smeltery, both require a solid + solid so probably not

Implement fluid behaviors (#4295)

Cool fluids all now extinguish fire and act more thick (since they are mostly slime and alike)
Hot fluids now are marked as lava path types
Hot fluids now damage you and apply fire
Various cool fluids now apply mob effects when inside

Json Things support for burning fluids

Update freezing and fiery descriptions

Release 3.8.3
