Top Face of Deepslate in Current Generation Is Multi Directional

Summary: Minecraft Bedrocks Deepslate Generation isn't bidirectional or west and east like Java instead of being limited to west and east Deepslate can generate in all directions for the top texture/face of deepslate creating weird and unnatural looking deepslate generation.

Steps to Reproduce:
Step 1: Load a World.
Step 2: Compare Deepslate Generation.
Step 3: Repeat.

Observed Result: Deepslate can generate in 4 directions in Bedrock instead of the two in Java.

Expected Result: Deepslate should only be able to Generate in two directions on Bedrock to align with Java's Deepslate Generation.
