Fix formatting issue of TopicPartition that causes SystemError on Windows

[fangnx]

What

Minor fix to address the formatting issue of TopicPartiton: CFL_PRId32 macro expands to "I32d" on Windows (MSVC), which is not supported by Python's PyUnicode_FromFormat(). To fix it, we will replace CFL_PRId32 with %d. This is safe as partition is already declared as int in the struct

Pull request overview

This PR fixes a Windows-specific formatting issue in the TopicPartition string representation. The CFL_PRId32 macro expands to "I32d" on Windows (MSVC), which is incompatible with Python's PyUnicode_FromFormat() function, causing formatting errors.

Key Changes:

• Replaced the CFL_PRId32 format specifier with %d in the TopicPartition_str0 function, which is safe since the partition field is declared as int in the struct.
