Description of the Change

This pull request standardizes the license references throughout the codebase and documentation, updating them from "New BSD License (BSD)" or "BSD 2-Clause" to the SPDX-compliant "BSD-2-Clause" format. It also updates license URLs to point to the official SPDX page for clarity and compliance.

License reference updates:

• Updated all PHP class files and headers to use "BSD-2-Clause" instead of "New BSD License (BSD)" or "BSD 2-Clause", ensuring consistency and alignment with SPDX standards. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13]

• Updated all @license annotations in docblocks to reference "BSD-2-Clause" and the correct SPDX URL, replacing old references to the BSD license page. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14]

Documentation and metadata updates:

• Updated readme.txt and windows-azure-storage.php to use "BSD-2-Clause" and the SPDX license URL (https://spdx.org/licenses/BSD-2-Clause.html). [1] [2]
• Corrected the license badge in README.md to match the new SPDX-compliant license name.

These changes improve clarity, legal compliance, and consistency for anyone referencing or distributing the project.
