Support Stable Diffusion 1.4 on Blackhole

All components: https://github.com/tenstorrent/tt-metal/tree/main/models/demos/wormhole/stable_diffusion/tt

Concluding with downsample and midblock tests (PR) , we will have unit tests for all SD components, currently working on Wormhole. Each component needs to be tested on Blackhole and fixed if needed. The following order goes from the simplest components to the more complex ones:

• upsample nearest - works unchanged; to check configs
• upsample - works unchanged; to check configs
• downsample - works unchanged; to check configs
• embedding - works unchanged; to check configs
• feedforward - works unchanged; to check configs
• geglu - works unchanged; to check configs
• cross attention - works unchanged; to check configs
• basic transformer block - works unchanged; to check configs
• transformer 2d - layernorm op grid error (affects cross attn down/up blocks)
• resnet - pcc issues (affects down and up block)
• downblock - pcc issues
• upblock - pcc issues
• midblock - layernorm op grid error
• cross attention down block - layernorm op grid error
• cross attention up block - layernorm op grid error

Note: Even components that work out of the box need to be double checked since sharding schemes and other configs might be changed in other components affecting them.
