Add Azure Ranker Component

Is your feature request related to a problem? Please describe.
We have OpenAIChatGenerator and AzureOpenAIDocumentEmbedder components in Haystack. In addition we have Retriever components in the Azure AI Search Haystack integration. However, we don't have a component that covers ranking with models served via Azure AI.

Describe the solution you'd like
We should add a new component that enables users to rerank documents with cross-encoder models served via Microsoft Azure. I believe this new component could become part of the existing Azure AI Search integration or become a separate integration depending on dependencies it might require. If it does not require azure-search-documents then it could become a separate integration where we have a Ranker Component and in future also an Embedder component.

AmazonBedrockRanker can be used as an example and the new AzureRanker or AzureAISearchRanker component should work as a drop-in replacement of AmazonBedrockRanker. @bglearning could provide feedback.

Additional context
My understanding is that the Azure AI Search service feature of a semantic ranker as described in https://learn.microsoft.com/en-us/azure/search/search-get-started-semantic?pivots=python is completely separate from this GitHub issue. We are looking for a ranker component that works independent of how the documents are stored and what index they use.
