Subject: [PATCH] Cache part of canHoldFluid result
Cache the result of part of canHoldFluid logic, since there are many state#is in canAnyHoldFluid method,
it uses map contains to do iteration to check whether a block has a specific block tag key,
which the contains iteration call is very expensive if called everytime
In the test, it can improve ~30% performance in ~1577000 times of canHoldAnyFluid calls (~159ms -> ~111ms)
