[MC-296112] execute unless block fails outside of build limit

Observed behavior

/execute if block ~ 320 ~ #minecraft:air run say air
/execute unless block ~ 320 ~ #minecraft:air run say not air

Both commands will fail rather than the test.

Expected behavior

/execute unless block ~ 320 ~ #minecraft:air run say not air

-> not air

As the block is not in the #minecraft:air tag, it’s the expectation that the command runs through completion.

Why it’s a problem

It’s non-trivial (not impossible) to deal with failing execute commands that run at arbitrary positions.

In case it’s useful for anyone since this was WAI’d.

predicates are not affected by invalid positions, where execute is. execute if|unless block has three states, true|false|exception, location_check predicates have true|false.
