Infer same directory dependencies for Thrift (Closes #15152)

[coderay3000]

Problem

Thrift dependency inference was failing to infer dependencies on other Thrift files residing in the same directory when included without explicit relative paths, leading to unresolved dependency warnings or missing targets.

Solution

• Updated infer_thrift_dependencies in dependency_inference.py to resolve same-directory includes alongside standard module mapping.
• Added test_infer_same_directory_dependency in dependency_inference_test.py to ensure same-directory Thrift files are correctly inferred as target dependencies.

Result

Same-directory Thrift includes are now automatically inferred, improving dependency resolution for Thrift source targets.

Closes #15152
