Subject: [PATCH] Fix UT compilation errors with GCC 13 due to missing
 <cstdint> includes

GCC 13 no longer transitively includes <cstdint> from other standard
library headers. This causes compilation failures for code using types
like uint32_t and uintptr_t without explicitly including <cstdint>.

This commit adds the missing #include <cstdint> directives to:
- test/baidu_thread_local_unittest.cpp
- src/bthread/list_of_abafree_id.h

The errors were:
- error: 'uintptr_t' was not declared in this scope
- error: 'uint32_t' does not name a type

This change ensures compatibility with GCC 13 while maintaining
backward compatibility with older compiler versions.
