Add beforeEvents for entityHitBlock in Bedrock Script API

To the Minecraft Team,

Currently, entityHitBlock is limited to afterEvents, so it is not possible to intercept or cancel left-click/hit actions on blocks before the engine processes them.

When attempting to protect custom interactions or handle entity-like blocks (such as item frames), playerBreakBlock and playerInteractWithBlock are insufficient due to differences in behavior between Creative and Survival modes, as well as differences in the engine-level processing order.

For creators who need to precisely control interactions triggered by left-clicking (punching/hitting), the implementation of beforeEvents.entityHitBlock with a cancellable event context (ev.cancel = true) is essential.

We kindly request that you implement beforeEvents.entityHitBlock in a future API version.

Thank you for your consideration.
