Add support for building with ICU 75.1 or later (#6486) 
* Add support for building with ICU 75.1 or later

We use ICU via libxml2 implicitly. ICU 75.1 or later require C++17 for
its C++ API:

https://github.com/unicode-org/icu/releases/tag/release-75-1

> C++ code now requires C++17

But we use C++17. So `#include <libxml/xmlreader.h>` with ICU 75.1 or
later causes an error:

We don't need ICU C++ API. So we can avoid this error by disabling ICU
C++ API by defining `U_SHOW_CPLUSPLUS_API` as `0`.

Azure Storage libraries for C++

Azure Storage is a Microsoft-managed service providing cloud storage that is highly available, secure, durable, scalable, and redundant. Azure Storage includes Blobs (objects), Queues, and Files.

  • Azure.Storage.Blobs is Microsoft's object storage solution for the cloud. Blob storage is optimized for storing massive amounts of unstructured data that does not adhere to a particular data model or definition, such as text or binary data.

  • Azure.Storage.Queues is a service for storing large numbers of messages. A queue message can be up to 64 KB in size and a queue may contain millions of messages, up to the total capacity limit of a storage account.

  • Azure.Storage.Files.Shares offers fully managed file shares in the cloud that are accessible via the industry standard Server Message Block (SMB) protocol. Azure file shares can be mounted concurrently by cloud or on-premises deployments of Windows, Linux, and macOS.

  • Azure.Storage.Files.DataLake includes all the capabilities required to make it easy for developers, data scientists, and analysts to store data of any size, shape, and speed, and do all types of processing and analytics across platforms and languages.

  • Azure.Storage.Common provides infrastructure shared by the other Azure Storage client libraries like shared key authentication and exceptions.
