feat: Add DisableBlockUpdateFlag

[AerWyn81]

Description

Challenge

Using the current disable-physics flag doesn't suit all needs.
I'm missing a flag that prevents blocks around one that I'm updating from being updated.

There are several examples:

• I put a flower on a block, I break the block, I want the flower to stay in place,
• I modify a wall with the debug stick, I break a block, I don't want the wall to update,
• I modify a stair with the debug stick, I break the block, I don't want the stair to change direction.

Resolution

In this PR, I've added the disable-block-update flag to disable block updating when blocks are updated. The default value is false because there shouldn't be any change in the update behaviour on a plot without a flag.

Two points:

• I haven't added the existing disable-physics flag because, as I see it, the two flags have their own responsibilities, one affecting the gravity of the blocks and the other the update.
• the flag doesn't block the updating of a block when snow is placed on it so that the block is covered in snow. I thought it should remain vanilla.
