chore: remove batch-related APIs

Browse source 
APIs removed:
 - POST /v1/batch-inference/completion
 - POST /v1/batch-inference/chat-completion
 - POST /v1/inference/batch-completion
 - POST /v1/inference/batch-chat-completion

note -
 - batch-completion & batch-chat-completion were only implemented for inference=inline::meta-reference
 - batch-inference were not implemented
